hi list,

last week i encountered an xfs error, related with nfs and was told to
use a newer kernel (subject was: "oops with xfs / nfs"). hm, shiny new
kernel is 2.6.7-bk17 and today i got an oops again:

again it starts with "kernel: nfsd: page allocation failure" - should i
send this to a nfs-list or lkml instead? but it always seems to happen
with xfs. nfs-load was not so heavy this time. the system is (as last
time) still usable, at some point i can tigger asystem lockup now, so a
clean reboot is a good idea...

i wonder what the real issue is here....

Thanks,
Christian.
