I am testing 2.6.30-rc8 on the server that has issues with 2.6.29.4,
I'll most likely know tonight or tomorrow morning if that kernel fixes
it.. I noticed a lot of xfs changes in rc8 so I figured it was worth a try.

Can you please also run with CONFIG_XFS_DEBUG enabled so that all
kinds of asserts might trigger?

The help for that option says the "code will be HUGE and SLOW"
How much of a slowdown are we likely talking about?

I haven't actually measured it, but it shouldn't be that bad. Mostly
it's adding tons of ASSERT statements. The Kconfig help is there to
prevent people from enabling it just because they can.

I've enabled that as of yesterday and I'll let it go through it's normal
operations.. It did survive the other night without CONFIG_XFS_DEBUG
on(and on 2.6.30-rc8), but that sometimes happened anyways.
If it makes it through this weekend without crashing then that bodes well
for something being fixed in the recent rc's.
Doesn't seem to be any slower though, the backups completed around the
same time as they always do.

Is your machine still happy ?
If so, I'll give 2.6.30-rc8 a shot, as well.

OK. running 2.6.30-rc8-git2. no crashes, so far.
but, same problem as with 2.6.29: tons of 'reconnect_path: npd != pd" messages
and stale NFS handles on the client boxes (i.e. my desktop).
I upgraded from 2.6.25, which worked fine.
The box is an AMD K8 (x86_64) with sata,raid6,lvm,xfs,nfsd.
