[asterisk-users] asterisk 1.4.26.3 makes kernel panic

[Vieri]

Hi,

I'm experiencing "frequent" kernel panics on a system with Asterisk 1.4.26.3.
There is no core dump, "just" a kernel panic.
This is the only data I could copy from the screen:

EIP: 0060: [<f8e248b4>] Tainted: P VLI
EFLAGS: 00210297 (2.6.23-gentoo-r8 #1)
eax: 00000130 ebx: 00000000 ecx: 00220028 edx: 00000978
esi: 346e5802 edi: 00000000 ebp: c3b45500 esp: caf05bfc
ds: 007b es: 007b fs: 00d8
gs: 0033 ss: 0068
Process asterisk (pid: 7631, ti: caf04000 task: f7987000 task.ti: caf04000)
Stack: ...
Call Trace: ...
Code: ...
EIP: [<f8e248b4>] ss:esp 0068:caf05bfc
Kernel panic - not syncing: Fatal exception in interrupt

As you can see, kernel is 2.6.23 but it's the same as on another server I have but with asterisk 1.2. Kernel 2.6.23 does not panic with asterisk 1.2. The hardware on both servers is identical (isdn cards, pri card, etc.) except for the motherboard.

How can I further diagnose the problem (besides, I think I can easily reproduce it as soon as I set it up as the "production" server)?
What can be causing the kernel panic?

BTW, the last "log entry" I have in /var/log/asterisk/full is:
[Nov 18 10:08:20] VERBOSE[6627] logger.c:   -- dialparties.agi: Checking CW and CFB status for extension 6169

(this system runs freepbx)

Help greatly appreciated.
