Thanks, didn't think of that one. Just installed it, thanks for the tip. I'll report back in few days with new status.

This time it froze after 1.5 days only. Here are the last line from system log:

Jan  6 01:30:01 iskon-valent root: I'm alive


I added two crontab tasks, one every 15 minutes saying "I'm alive" and other logging uptime every hour, as you can see from the logs not even latest rawhide kernel did any good. Any other ideas?


Just to report back, now with rawhide kernel freezes are much more often, both were around 1.5 days and before I could go for 4-8 days before freeze:
