Sorry, but the affected computer is in production and not available for
further testing. I (reluctantly) switched to the proprietary nvidia
driver as a workaround, and that worked out to the user's satisfaction.
As with all problems that have only been observed on one machine, one
wonders whether it might have been a hardware issue. I forgot to
mention that this Dell PWS 390 was then running BIOS 2.3.0 and logging
kernel: mtrr: type mismatch for d0000000,8000000 old: write-back new: write-combining
on a regular basis. I have since upgraded to BIOS 2.5.0, which got rid
of the MTRR warnings.
Under the circumstances I don't expect you to spend much time
investigating this bug report, but I thought I'd document my findings
anyway for the sake of the next person who runs into the same symptoms.
