Comment 9 for bug 115275

Okay. I did the change described above and all i can say for now is that the next boot after the change, the system came up without problems. It is also running stable for more than 30 minutes now.
Unfortunately that doesn't mean anything because sometime, after 10 - 20 crashes, if the system ran stable for more than ~30 minutes, it will run stable for the rest of the day.
So, to answer your question, it seems to have something to do with powernowd, because today i had only 3 crashes before i did the change. Compared to the usual behaviour, this is a suprising low crash rate!
Though i can only provide a correct answer in about 24 hours from now on.

It may be interesting to hear the results of other people in here.
Thanks for the suggestion. I keep my fingers crossed!
