I applied the patch provided by EclipseAgent (comment #15) and Compiz is
now working again on my T2300 CPU with nVidia 7400 Go GPU. To install
the patch, I used the DKMS approach: just put the patch file in the

+1: Compiz is also not working for me since the upgrade to Karmic.
Jaunty was fine though. I attached the contents of /proc/cpuinfo in case
this helps.
Otherwise, Karmic rocks :-)

Alberto, that appears to be correct. My CPU does not support PAT and I
have this problem.
While the workaround patch may not be "fit" for general release, it is
effective for the time being and it's pretty trivial. Any chance of
including it until nvidia decides to make their driver behave with
2.
ok, so the problem seems to affect CPUs which do not support "pat" (mine
does it).

The GPU is largely irrelevant (other than being an nVidia card), the bug
stems from an erratum, at least affecting the Intel T2500. The nVidia driver
was relying on certain behaviours in the kernel pertaining to the CPU which
changed in 2.6.30.

I'm not clever enough to know if the change in the kernel constitutes a

Yes, as linked in my original posting with the code it is from NVIDIA.
Why should it be fixed in the NVIDIA driver when the problem is the
kernel? The regression was from the kernel and PAT isn't functioning
correctly in general.

it is the kernel.. it's the method of PAT forcing back to MTRRs, so this

A kernel regression is less likely I think, you'd see problems all over
