Description of problem:
System crashes due to a NULL pointer dereference when trying to reboot it.
The faulty address seems to point to the sunrpc module, if I am not mistaken:
IP: [<ffffffffa00f6391>] rpc_create+0x401/0x540 [sunrpc]
Version-Release number of selected component (if applicable):
Linux Kernel 3.5.1 (64 bits)
I have experienced this twice in the last 5~6 reboots.
Steps to Reproduce:
1. Reboot from GDM login screen
System does not reboot, but changing to a text console a BUG report can be seen.
System has recently been PreUpgraded from F16 to F17 (no issues during the upgrade).
There are some NFS mounts and it uses NIS to authenticate too.

cc'ing Stanislav since this looks like it might be related to his namespace changes.
Looks like this is the same problem that Stanislav pushed a patch upsteam for earlier in the week. Closing as a dup.
