Public bug reported:
Binary package hint: linux-image-2.6.17-50-generic
I experience the kernel oopsing in the context of the 'mount' process
when I:
(maybe related)
# echo 43407 >/proc/sys/fs/nfs/nfs_callback_tcpport
# mount x1.home:/ /store -t nfs4
This works perfectly on 2.6.19. Version is Edgy with current updates and
proposed 2.6.27-50 kernel - i686 arch.
The kernel logs contain:
