Public bug reported: Binary package hint: linux-source-2.6.24
I've several automounted NFS mounts which have worked for years. They are currently causing a Oops which locks the processes involved, including nautilus and gnome-panel (presumably by way of gvfs?). I've added uname, dmesg, dmidecode and lspci output to https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.22/+bug/214810 which appears to be the same oops, only on 2.6.22.
