BUG: unable to handle kernel NULL pointer dereference at 00000108

[Uli Heller]

I am using ubuntu10.04 netbook edition on a eeepc 701.

I think I can reproduce the bug:

1. Boot into the desktop using "auto login" (so no username/password prompting)
2. Open a terminal window by pressing ctrl-alt-t
3. Try to execute any command in there, for example "ls"
4. System crashes when pressing the enter key

The bug does not happen if you do not use the "auto login".
