Hmmm, I have just had two nasty problems with X the last two days. The
first went unnoticed in the logs, but yesterday I got the following in
the logs. It seems strange to me to get an oops with mixed information
from XFree86 al PPP support.

*BIG FAT WARNING*, VMware modules were loaded, so take the following with a
BIG grain of salt:

Kernel version is 2.6.0, XFree86 is 4.2.1-9 and libc 2.3.2.ds1-10, all from
Debian Sid, not updated too frequently, to say the truth :)

Hope it helps.
