No updates, no new hardware. What I did yesterday is I installed sickbeard and couchpotato.
I have my filesystem on an USB HDD, not SD, forgot to mention.
I think it started showing up when hdd was under stress (unraring several files) but connect test it now...

These sort of errors are normally associated with power issues.

Post the full dmesg via pastebin as requested in Please read before you post

As I rebooted it's not visible in dmesg anymore, will wait for second chance.
For the power supply it's not that. I have LaCie HDD and never had such problems when connected to other systems. For RPI I have HP Touchpad 2A/5V, tested it and voltage is correct, also this adapted was recommended by others.
