Subject: Opss: 2.6.21-1.3116.ONELAN Kernel last sysfs file: /class/vc/vcsa7/dev

I'm testing the robustness of Xorg 1.3 server with intel 2.0 driver
by restarting the X and a set of apps every 30 seconds. After
about an hour this happened.

2.6.21-1.3116.ONELAN is the same as 2.6.21-1.3116 from FC7
but with the spec file change so that we can run the kernel on an FC4
system.

eth0: no IPv6 routers present
BUG: unable to handle kernel paging request at virtual address 6b6b6b6b
 printing eip:
