kernel panic - not syncing: Fatal exception in interupt

kernel panic - not syncing: Fatal exception in interupt

[shaun]

+Hardware Specs
Dual Xeon 800FSB
Intel Server Board
4GB ECC DDR
3ware 9500 Sata Raid Card
5x200 GB sata drives in a raid 10 Config (1 hot spare)
Dual Nic

+OS Specs
CentOS 3.4 running a custom 2.6.x kernel patched with UML SKA's Patch
eth0 is 0.0.0.0 promisc and assigned to a bridge (br0)
tuntap devices up
ebtables is enabled and loaded with rules

My problem is that every other week or so the machine crashes.  It never
dumps the error to the logs so all i have is a screen shot of the console.
I have put some serious stress on this machine and have been unable to
duplicate the problem (running 20 guest UML's half running va-ctcs and the
other half compiling a 2.6 kernel).   Below is a link to 2 screen shots i
have (about 2 weeks apart).  I started off using a 2.6.10 kernel when the
problem started.  Last time the machine crashed i built a 2.6.11.5 kernel
and disabled APM and ACPI in the kernel config.  Any body know whats going
on here.

Is it possible to run without the bridge for testing purposes, and be 
sure to put the normal networking load?

No, sorry, i have to run with bridging support other wise the guests(UML's)
wont be able to communicate with the outside world.

Ok in that case, can you connect a serial console so that you can capture 
the entire output?

Thanks,

Re: kernel panic - not syncing: Fatal exception in interupt

[mailinglist@unix-scripts.com]

The last time i crashed i changed the console resolution, i'm hoping it will
give me the whole dump this time.  I will see if i can get a serial console
on it.

Re: kernel panic - not syncing: Fatal exception in interupt

The machine crashed again twice today.  I have vga=791 so i caugh a bit more
of the crash.  i enabled serial redirection in the bios so i'm hoping to
catch the full dump next time.


The first screen shot is with the old resolution so didnt catch much more
here...
http://www.unix-scripts.com/shaun/host1-2005-04-12-01.png

But this screen shot got a nice chunk and looks a bit diffrent.
http://www.unix-scripts.com/shaun/host1-2005-04-12-02.png


Still looks like there is alot more that i'm missing but by glancing at that
dump, to me it definitly seams like bridging is causing this.  I'm going to
post this to the ebtables lists tomarrow also.

Best Regards,

Shaun R.

Cool, can you also try Cc'ing netdev@oss.sgi.com?

This was fixed about a month ago.  Here is the patch that did it.

Perhaps it's time to include this in 2.6.11.*?

Re: kernel panic - not syncing: Fatal exception in interupt

[Shaun Reitan]

I actually ran accross that patch this morning on the ebtables lists but i
wasnt sure it would fix the problem i was having.  I will get this patched
into the kernel and see what happens.  Thanks  for the responce, if this
went on much longer this $4,000 machine was going to become a paper weight
:)

Shaun Reitan

Is there a way i can trigger this bug rather than waiting for it to happen?
I would like to make sure it's not going to crash on me again.

Applied to the -stable queue, thanks.
