Kernel panic 4-5 Nov (i386)
-
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)
built on Tue Nov 9 17:26:01 UTC 2010 -
pfSense-Full-Update-2.0-BETA4-20101109-1641.tgz
-
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.
