Hi,

Booting 2.5.43mm1, I get the following oops:

Unable to handle kernel paging request at virtual address 00002004
 printing eip:

*pde = 00000000
Oops: 0002

CPU:    0
EIP:    0060:[<c01a1ddd>]    Not tainted
EFLAGS: 00010246
Quoted 1 line

EIP is at nfs_proc_fsinfo+0x6d/0x110

Does it happen on 2.5.43?

I've been getting some strange NFS oopses too. I haven't bothered to catch them yet, but they happen without the -mm changesets for me.
