My oopses were not related to nfs or xfs. I don't use either of these
on this box.
In the interest of contributing more than conspiracy theories, I'm
trying to dig up some records of the dcache problems I was having.
Unfortunately, a period of low free disk space led to some aggressive
"cleaning" on my part since then. :(
I _was_ able to find the attached oops, but I don't think I have the
corresponding object files, so I hope the decoding it contains is
good enough.
Just ask if you need some more info.
