[Bug 535338] [NEW] BUG: unable to handle kernel NULL pointer dereference at 00000108

[Oliver Gerlich]

Public bug reported:

No idea what caused this... the Apport indicator suddenly appeared and
showed this Oops.

This happened on Lucid Alpha 3 Netbook Edition likely with all updates,
on an Asus EeePC 701.

Don't know if this is related, but there are X crashes happening all the
time; from Xorg.0.log.old:

Backtrace:
0: /usr/bin/X (xorg_backtrace+0x3b) [0x80e883b]
1: /usr/bin/X (0x8048000+0x61b1d) [0x80a9b1d]

6: /usr/bin/X (0x8048000+0x1e931) [0x8066931]

Caught signal 3 (Quit). Server aborting


As far as I can see this oops occurred only once so far. Unfortunately I had to reboot (for other reasons) before reporting this oops, so not sure if the additional info captured by Apport is useful.
