Bug#413676: linux-image-2.6.18-4-ixp4xx: nfsd oopses with 'unable to handle kernel paging request'
Package: linux-image-2.6.18-4-ixp4xx
Version: 2.6.18.dfsg.1-11
Severity: normal
I have a directory exported with nfs-kernel-server. I can mount it OK, but writing to it causes an oops. After writing about 5MB, nfsd dies with the following oops:
Unable to handle kernel paging request at virtual address 000123c8
pgd = c0004000
[000123c8] *pgd=00000000
Internal error: Oops: 17 [#1]
