--- Comment #10 from Andrej.Skvortzov at gmail.com ---
I have this issue as well when I am testing latest mainline kernel on my
Squeeze machine. With the stock 2.6.32 kernel system can run almost for ever. I
confirm that this bug happens pretty random. System can run couple of days
without an issue or only couple of minutes sometimes. The reason is not clear
for me too. Sometimes I just read something on the web and do nothing special,
sometimes it happens when I am starting app.  

I will attach below my dmesg and crash dump. I hope this will help.
