[Bug 76155] Kubuntu 6.06 security update to linux-image-2.6.15-27-k7 breaks nVidia1.0.8776+2.6.15.12-1 Xorg crashes when exiting

[Jg-jguk]

Public bug reported:

Binary package hint: linux-image-2.6.15-27-k7

Adept prompted me to install some security updates, I saw one was a new
kernel. I installed it and rebooted.

The next day when I exited KDE my system locked up, I couldn't trigger a
reboot, connect it over the network or even Ctrl+Alt+SysRq S/U/B didn't
have any effect, so I had to hard reset.   I repeated this 3 times
trying "Log Out" the 3rd time, the result was the same.

This leads me to believe that linux-image-2.6.15-27-k7 security update
broke the nvidia binary driver

I logged the package details before I started attempting to resolve the
crash:

# cat linux.txt

I had to upgrade the system to 6.10 now as I could not leave this
machine crashing when exiting X.  I wish there was a way for the kernel
to avoid such fatal crashes, so at least it could give a backtrace or
log of what caused the problem.
