I've build new computer and installed openSUSE 13.1 on it. It has Intel DH87MC motherboard and Intel Core i7-4770K. Problem is that it sometimes (after 10-30 hours) hangs, it responds to ping, but that's all, ssh doesn't answer, apache doesn't answer, input from keyboard is ignored, power button only wakes up from screensaver. Only thing that can be done is reset. There are no messages in log files. And sometimes, it hangs just for while and shows messages like: kernel:[ 1594.865752] BUG: soft lockup - CPU#1 stuck for 22s! [btrfs:3134].
I've tried to switch off everything unnecessary in BIOS, I've tried new kernel from kernel/stable, but nothing helped. I'm suspecting that there is something wrong with motherboard, but I'd like to be more sure before buying new one. So my question is: Are there some ways how to diagnose what's causing the hangs?
