(Get the code!)
Well, since switching back to my .30 ultimate kernel from the .29-5 generic, I have gone four days without a sudden freeze to black crash. I don't know why I'm having this space of good luck, but I reluctant to fiddle with anything.
Incidentally my kernel log still shows tsc clocksource unstable.
I think there are two basic types of freezes going on here: one is sudden and without warning, where the screen goes to black or the dominant window color, there may be mouse movement, or not, but all one can do is hit the power. The second kind involves very high processor use, rising temps, sluggishness, and freezing of the system. In this case, if one is quick enough x can be restarted or the offending program can be terminated through the keyboard.
It may be helpful to describe just which of these types of freezes you experience when it happens. They could be related to the same cause, but they mightn't be, too.
