Subject: nfsd oops with 2.6.5-rc2-mm4
Date: Sat, 27 Mar 2004 14:07:35 +0100 [thread overview]
Message-ID: <20040327130757.GA6760@c9x.org> (raw)
Hello.
I got a reproducible oops after a few minutes with a 2.6.5-rc2-mm4 kernel.
/etc/exports :
/mnt/data 10.42.42.0/24(rw,async,no_subtree_check,root_squash,
anonuid=10000,anongid=10000)
Clients are 2.6.5-rc2-mm2 kernels, filesystem is ReiserFS 3, data=writeback.
Exports are mounted with tcp,nolock,soft,timeo=600,retrans=2,actimeo=30,
rsize=32768,wsize=32768.
Once the oops has happened, no client can access the mount point any more.
Unable to handle kernel NULL pointer dereference at virtual address 00000004
printing eip:
