In my early troubleshooting efforts I set the performance mode
and if I recall there was no problem. When I set powersave it crashed
few seconds later.
Here are the last lines from the log shortly before crash:

I also found something interesting in the pm-powersave.log:
Running hook /usr/lib/pm-utils/power.d/wireless false:

Management" (8B2C) :
