Just want to let you know that I had tried that (doing much IO, doing
graphics, changing graphics drivers and acceleration modes) with my
D610 and did not succeed making the problem appear deterministically.
Since Win works perfectly, I guess it's a strange timing/scheduling
error in the kernel. The fact that moving from 2.6.10 to 2.6.12
improved the situation seems to confirm that. (Note that the D610 has
a relatively new chip set and it's not unlikely that the kernel guys
have still some bugs sitting in their code.)
Unfortunately, I have no idea how one would debug such a problem: When
the machine locks, it locks completely. No kernel messages, no error
screen, no ssh. It's dead.
Yours,
Matthias
