2.6.3: oops reading /proc/net/rpc/auth.unix.ip/content

[Burton Windle]

Hello.  I just upgraded a workstation from 2.6.2 to 2.6.3, and am now
seeing an oops on boot when my init scripts run the nfs-kernel-server
script. The oops actually happens whenever trying to read
/proc/net/rpc/auth.unix.ip/content


Linux version 2.6.3 (root@jekyll) (gcc version 3.3.2 (Debian)) #11 Mon Feb 23 22:23:26 EST 2004

Unable to handle kernel NULL pointer dereference at virtual address 00000044
