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

Jesper,

In the short term, the best workaround is to use 8K stacks. We do not see stack
overflow problems with NFS + XFS + volume managers + disk devices.

Audits have been done in the past and will again be done in the future to try to
identify areas where XFS could use less stack space by reducing/avoid large
local variables. Reducing the code path is far more difficult.

There is active discussion about reducing inlining:
http://bugzilla.kernel.org/show_bug.cgi?id=7364

I can't speak for the scsi stack usage.

Thanks for traces, I've captured this information.

Thanks,

David
