Kernel panic 4-5 Nov (i386)

CryoGenID

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.

CryoGenID

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.

Running on a Soekris 5501.

Give a shot at tomorrows snapshots.

Wahoo! Thanks ermal!

coming from my own thread :
http://forum.pfsense.org/index.php/topic,30207.msg157592.html
Unfortunately, using latest available snaphost, the crash repeats, after 1 or 2 minutes uptime

FisherKing

Yeah - I installed the 2010-11-25 update and experienced the same thing.

Ermal - do you need a backtrace from the current snapshot, or is what you have already sufficient?

Hi,

doesn't look good yet, using the snapshot from yesterday (sullrich@FreeBSD_8.0_pfSense_2.0-snaps.pfsense.org, Thu Nov 25 10:39:16 EST 20).

I just created the first LAGG interface from vr2 and vr3 on my Soekris 5501. Immediately after clicking the apply button in the web interface:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0xc
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc09bbc2d
stack pointer = 0x28:0xe5dbec04
frame pointer = 0x28:0xe5dbec24
code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 11 (irq9: vr2)
trap number = 12
panic: page fault
cpuid = 0
Uptime: 17h58m38s
Cannot dump. Device not defined or unavailable.

Hmmm sorry i thought i had pushed the patch to repo!
Just did though try with next snaps.

Is this probably the same issue that hits me here: http://forum.pfsense.org/index.php/topic,30465.0.html

Hi,

@ermal:

Hmmm sorry i thought i had pushed the patch to repo!

just to give a quick head-up: I have tried the latest snapshot and it seems to have fixed the problem. No kernel panic yes with extensive VLAN on LAGG interfaces config fiddling (but no actual traffic over these yet).

Thanks for fixing this,

Martin

same here
uptime 2 hours and increasing :)

thanks a lot once more for the hard and continuous work

Still not possible for me to add my second wireless interface…

See http://forum.pfsense.org/index.php/topic,30465.0.html

Still rebooting then...

eri--

Go over to your thread jlepthien do not hijack this one.

jlepthien

Well, doesn't this look kinda the same problem? And since you are the one fixing this I thought you might be interesting. If you do not want the info on bugs I'll happily install 1.2.3 again and leave the testing up to you…

CryoGenID

Unfortunately, I am still fighting with the kernel panic :'( :'( :'( :'(

I had hopefully upgraded to "Sat Nov 27 03:13:22 EST 2010 "-Build via USB-Stick, which worked pretty fine.
Today, I tried to use the built-in update feature and… BANG! Kernel-Panic (Fatal Trap 12), see attached screenshot...
(the screenshot is from an older build, but the error is still the same)

ermal, are you still fighting this problem? :-)

Hopefully there will be a solution soon :)

Best regards,

Christian

without a backtrace i cannot say that this is related to this.

I tested both the 27th and 29th snapshots, doing an upgrade to the 27th and then a clean install for the 29th. Kernel panic still pops up for me under the same conditions as before. Oddly, the panic doesn't happen until after the update / install has been in place for a while (1-4 hours?) If I install an update, both GUI and fetch and will work for a bit, then a couple hours later, I run fetch from the console or log into the GUI again and it bonks almost immediately.

I'll get a current backtrace for you in the next hour or two.
