Hello. I'm using the automounter under 2.2.10 with some NFS patches
applied to the client, and I've started getting the following oops
out of some of the machines (and subsequent NFS hangups on that
automounted directory):

Sep 16 18:46:16 luc0147 kernel: Unable to handle kernel paging request at virtual address 07479749

Note that I do sometimes see lots of this type of output:

Sep 16 18:43:57 luc0147 kernel: nfs_dentry_delete: file.blah.ino: ino=11085, count=2, nlink=1

but I was told those are debugging messages and to ignore them.

Anyone have any ideas? This is 2.2.10, x86, SMP.
