2.6.19-rc6 : Spontaneous reboots, stack overflows - seems to implicate xfs, scsi, networking, SMP

Hi,

I have a server that has long suffered from spontaneous reboots and random
crashes.
The problems seem to be partly SMP related since the machine is rock solid
with a UP version of 2.6.11.11, but the same kernel compiled for SMP has
issues.

The server initially had 1 Intel Xeon CPU with HT and was very recently
upgraded with an additional one (in the blind hope that the issues would be
fixed). The kernel *seems* to die faster with 2 CPU's and a SMP kernel than
it previously did with just one (HT) CPU and a SMP kernel.

I've been trying newer kernels, such as 2.6.17.x, 2.6.18.x, 2.6.19-rc*
(all SMP), hoping that the problem(s) would be fixed, but that does not seem
to be the case.

Recently I've been using netconsole and have lots of debug options enabled
in the hope that I could capture some relevant info. Unfortunately nothing
ever really made it to the remote log - except one little incomplete bit I
got the other day (with 2.6.19-rc6) :

do_IRQ: stack overflow: 492

That is all that made it to the log, but it does indicate that the problem
might be stack-usage related.
Since the kernel was compiled with 4K stacks, perhaps if it was changed to
use 8K stacks it would stay up long enough for a complete dump to reach the
logs. But, if 8K stacks really did help, it would be nice if the dumps still
happened at the same point where they would have with 4K stacks.
So, I changed STACK_WARN in include/asm/thread_info.h from (THREAD_SIZE/8)
to(4608). This way I should get stack traces at the point where the kernel
would be in trouble with a 4K stack but since it's actually using a 8K stack
it should survive and let me capture the trace.

I got more than I could ever have hoped for. I still got spontaneous
reboots, but this time my remote log server captured tons of stack dumps.
I've got far too many to send here (more than 2G) and most of them are
identical anyway, so I'll just submit a few representative samples
initially.

Most of the traces include XFS functions and some also involve scsi and/or
networking. This is the reason I'm submitting this to the XFS & netdev lists
in addition to LKML.

All of these traces were collected with 2.6.19-rc6 with the modification
mentioned above.

Hardware details and software environment info is at the end of the email.

This is the most often captured trace :

This one seems to involve scsi :
