So far I do not have a reproducible test case,
Ok. What sort of load is being placed on the machine?
Hello, generally the load is low, it mainly serves out some samba shares.
It appears that both the xfslogd and the xfsdatad on CPU 0 are in
the running state but don't appear to be consuming any significant
CPU time. If they remain like this then I think that means they are
stuck waiting on the run queue. Do these XFS threads always appear
like this when the hang occurs? If so, is there something else that
is hogging CPU 0 preventing these threads from getting the CPU?
Yes, the XFS threads show up like this on each time the kernel crashed. So
far
with 2.6.30.9 after ~48hrs+ it has not crashed. So it appears to be some
issue
between 2.6.30.9 and 2.6.31.x when this began happening. Any
recommendations
on how to catch this bug w/certain options enabled/etc?
Cheers,
Dave.

Uptime with 2.6.30.9:
06:18:41 up 2 days, 14:10, 14 users, load average: 0.41, 0.21, 0.07
No issues yet, so it first started happening in 2.6.(31).(x).
Any further recommendations on how to debug this issue? BTW: Do you view
this
as an XFS bug or MD/VFS layer issue based on the logs/output thus far?
Justin.
Found root cause-- root cause is asterisk PBX software. I use an SPA3102.
When someone called me, they accidentally dropped the connection, I called
them back in a short period. It is during this time (and the last time)
this happened that the box froze under multiple(!) kernels, always when
someone was calling.
I have removed asterisk but this is the version I was running:
~$ dpkg -l | grep -i asterisk
rc asterisk 1:1.6.2.0~dfsg~rc1-1 Open S
I don't know what asterisk is doing but top did run before the crash
and asterisk was using 100% CPU and as I noted before all other processes
were in D-state.
When this bug occurs, it freezes I/O to all devices and the only way to recover
is to reboot the system.
Just FYI if anyone else out there has their system crash when running asterisk.
Just out of curiosity, has anyone else running asterisk had such an issue?
I was not running any special VoIP PCI cards/etc.
Justin.
