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.
