Well,
I did a lot of stress tests, and it seems to be pretty random, and what's
worse, I think it is more then one problem, oh great...
Seems that at least one of my NFS problems was in fact caused by ext4 regression
(what FS are you using?)
applying this one: http://bugzilla.kernel.org/attachment.cgi?id=24975
improved things for me a lot (see http://bugzilla.kernel.org/show_bug.cgi?id=15231 for
full discussion).
I'll watch the machine for next few days and report...
Is there *any* kernel (however old) on which you are confident you can
*not* reproduce the kref bug?
I have got a bug that looks a lot like this on 2.6.32.8 yesterday less
than 24 hours after booting the first 2.6.32 kernel but we have been
running on 2.6.31 for 3 months before, so I'm fairly confident that it
is a .31 -> .32 regression.
