Package: linux-2.6 Version: 2.6.36-1~experimental.1 Severity: normal Tags: upstream
Just this... I use a NFS4-kerberized setup with a debian based NFS server. The Oops happened after having tried to access a NFS share with GNOME nautilus. As my LAN is using IPv6 with the client having the IPv6 privacy extensions enabled, it might have happened after a temporary address became invalid. The share in question is mounted at boot time. On the server there are several lines like that in the kernel log (no idea if this could have its share, too): Nov 28 17:38:30 moah kernel: [176768.913791] RPC: AUTH_GSS upcall timed out. Nov 28 17:38:30 moah kernel: [176768.913794] Please check user daemon is running. This bug report is on an Oops on the corresponding nfs CLIENT. Maybe the server is setup in a wrong way, but I suppose the clients shouldn't oops under any circumstances. If there is further information needed, please contact me.
