Kernel panic 4-5 Nov (i386)
-
Unfortunately i can only confirm the kernel panic (page fault). It happens when booting, just after the interface configuration.
I am reinstalling a this moment to see if i can get the system working again.-m4rcu5
That sounds more like the amd64 problem, this is on i386.
jimp, i use the i386 image on a Intel core2duo.
I have the exact same fault code on the same process (only on interface em0) as pakjebakmeel. This time it happend when booted from the live cd.

-
For me it only happens when navigating the webGUI.. If I leave the GUI alone and generate massive traffic the box is rock solid.

Hi jimp,
Sorry for screenshots, but I use real hardware ASUS Pundit and have not serial console. Before my first post I wait panic maximum 5 minutes. Now on lasts snapshot more long, but I know differences between snappshots absent.
This panic was appear immediately after fetch command on pfSense host. -
Hi all,
Is this bug still present or can it be fixed by upgrading to a newer snapshot? 8)
Thanks!
-
It's still there. I just restarted the builder again to see if the fixes checked in yesterday made a difference. It should be done in a while but I'd still wait for an all-clear.
-
Current snap is OK:
2.0-BETA4 (amd64)

Ah, well I was hoping it may be a similar issue to amd64. Looks like it may be different.

Same balls, but side-view. It seems to me traffic generating by router is reason of crash. Without this traffic router working more long time, but attempt to fetch any by router always cause panic. -
I've been sitting here furiously loading GUI pages on my poor little ALIX running a snapshot from today and though it's gotten slow at times, I have yet to see a panic.
Is there anything else people in this thread might have in common? What kind of setups do you all have? Can you give a general idea of things that are in use? (Multi-wan, IPsec, OpenVPN, PPPoE, 3G, wireless, etc)
-
Not to cause you more frustration Jimp - but I'm seeing this GUI / Kernel Panic also.
Running 2010-11-09 (i386) on a PIII.
Reset to factory defaults yesterday & did a basic install
I've got 2 dual port intel nics.
fxp0 = WAN PPPoE
fxp0 = Opt3 DHCP private (10.x.x.x)
fxp1 = Opt1 DMZ static public
fxp2 = LAN static private (172.x.x.x.)
fxp3 = Opt2 static private (172.y.y.y)I'm running DHCP server on Lan and Opt2.
I'm logging in under a 2nd administrator account.
I'm running Captive Portal on Opt2 w/ local auth
Firewall allows web, mail, dns traffic through to the public IPs on the DMZ
I have freeswitch installed on the box, but it isn't the pfSense package. pfSense doesn't know it's there.How does this match up with what the rest of you have?
-
I've noticed the following on the kernel panic screen.
Cannot dump. Device not defined or unavailable.
Would the dump be helpful in diagnosing this? Is there a place where we can find directions on how to give it a dump device? Is it possible to dump to the local disk, or to a USB memory stick?
I do have a null modem cable & could dump to the serial port / windows terminal app if that's how it's done, but I'd need directions for that also.
-
Can it be your hardware?
Can you please install dev kernel in there? -
In case someone missed it earlier in the thread, here are instructions for installing a dev kernel:
http://doc.pfsense.org/index.php/Switching_Kernels
Afterwards, capture the panic message and also the output of typing "bt" at the debugger prompt.
-
Hi!
snapshot pfSense-Full-Update-2.0-BETA4-20101110-1837.tgz
I switching to dev kernel but is not working at all (can't finish boot). Attaching dmesg for hardware configuration.
Rollback to 13 Oct, because not working PPTP MPD is critically for me. -
Can you please try setting net.inet.tcp.syncookies=0 and see if you still get panic?
-
pfSense-Full-Update-2.0-BETA4-20101111-2017.tgz
I try setting net.inet.tcp.syncookies=0 in /boot/loader.conf.local and all without changes.
Dev kernel cannot finish init scripts and panic on “syncache: mbuf to small”.
Uniprocessor kernel working some time, but panic on interrupt routines (more often Ethernet bfe0 WAN, but may be clock interrupt).
I can post screenshots if it can be helpful. -
WOW that debug kernel is slow (on my PIII 500 Mhz)!
I got the dump, but it's a physical machine so all I could do is take pictures. For future reference, is there a better way to capture that dump? The machine does have a serial port.
pics attached.
-
I can confirm its not the hardware, i tried installing fresh install on 3 different pc, pentium 3 and 4.
-
I've found another way to produce the kernel panic and it seems to be related.
I've noticed that when I log into the GUI that pfSense doesn't panic until the automatic update check has completed. Related to that, if I ssh into the console and select option 13 (upgrade from console), and then option 1 (Update from a URL), the system will panic when it starts to download the file from the snapshot server.
Even stranger, if I ssh into the console, choose option 8 (shell), then then type something like "fetch http://snapshots.pfsense.org/FreeBSD_RELENG_8_1/i386/pfSense_HEAD/updates/pfSense-Full-Update-2.0-BETA4-20101115-1340.tgz" the kernel will panic then also.
My "WAN" port is configured via PPPoE. I've also set the physical port that the WAN is on as Opt 3.
Still having this panic on snapshot dated "Nov 15 16:00:39 EST 2010".
-
Ok, I figured out how to setup the serial console on the full version of pfSense.
Having done that, I've captured a couple of kernel panics and the back traces from that. I've noticed that the panics appear to be related to my WAN port. My WAN's IP is received via PPPoE.
The others who are seeing this panic - are you also getting your WAN IP via PPPoE? Or maybe PPTP? What driver is your WAN using?
Here are the kernel panics & back traces.

my wan is DHCP.
my pfsense was rebooting while downloading lightsquid.
it seems to crash only when the box itself is getting something from the internet.
slow dsl, or fast cable connection, same issue here i think.
-
Hi singerie - So it probably isn't PPPoE then. Thanks.
- are you running either Captive Portal or Traffic shaping?
- What network driver is your WAN using?
-
i'm not using captive portal or traffic shaping, but i use multi wan, but only as a failover.
My network card is a Intel pci-e.
-
I've seen similar panics in a build of 9-Nov. More in http://forum.pfsense.org/index.php/topic,29927.0.html
-
Same panic here: http://forum.pfsense.org/index.php/topic,30048.0.html
-
Beerman, Wallabybob, I'm curious, what nic is assigned to your WAN? Or what driver is your WAN using?
-
I'm using rl0 for my WAN interface. I could easily swap to vr0 or a wireless link or a USB NIC if you thought it worthwhile to gather some more data. I can reproduce my problem fairly easily.
-
My Alix 2c3 has this happen when updating and randomly at some other times when accessing the web gui. WAN is vr1 and uses only DHCP, LAN is vr0, and I have ath0 for an access point on OPT1.
PJ2: Some good information there. It looks like it is crashing in the same function at the same line of code every time, called from the same code path.
-
I swapped interfaces so vr0 was my WAN and on three restarts I've hit the same panic: syncache: mbuf too small
-
I had wondered if it was just an issue w/ intel nics. Sounds like it's not that specific. Thanks Wallabybob.
-
@PJ2:
Beerman, Wallabybob, I'm curious, what nic is assigned to your WAN? Or what driver is your WAN using?
My WAN is on vr2_vlan7. (ALIX Board)
-
Any updates on this already?
We are also facing this problem here…
We stumbled over this "bug" (or whatever it is) a few weeks ago, when we tried to update to the newest snapshot...
Normally we used to update every few days and then suddenly we got this "Fatal Trap 12"-Error during the update...It seems to be related to the update-system of pfSense, as it occurs either when checking for a new FW or trying to
download a new FW (using the Web-Interface or the Shell doesn't matter, the Trap comes anyway).
(I have attached a screenshot of our system)We are using pfSense on >10 boxes, all with the same HW.
We have already switched the complete HW, but the problem stays the same (so I doubt that it is related to HW).WAN1: ste0
WAN2: ste1
LAN: vr0Hopefully there will be a fix soon (as we want to be able to upgrade again, also because of the now fixed PPTP-Bug)...
Thanks a lot and best regards,
Christian

Hello everybody,
are there already any news on this?
As I can on other threads here, the "kernel panic"-problem seems to be happening to a lot of people…Is this a bug in FreeBSD itself oder pfSense?
Thanks and best regards,
Christian
-
I am looking into it and will post when a solution is checked in.
-
Perfect, ermal,
thank you :)
Best regards,
Chris
-
Yeah - thanks for looking into this ermal. It's hard to to much other testing when we can't do anything w/ the GUI. :)
Let us know if you need any other information. I can probably arrange remote access to the box if you can't reproduce this on your hardware.

Hi,
unhappy camper as well. Using the snapshot from 2010-11-18 I tried to configure an interface group, after this I got trapped in a kernel trap - reboot loop.
