Well the logs only show that separate hard drives stoped responding for
a while and kernel resetted sata link at that point.
Since it's happening on random drives, and even two at a time, I'd say
hard drives itself are not the problem. I'd replace power supply first.
I've had similar simptoms on one of my machines - it either crashed or
kicked one of drives out of the array. It happened randomly, but usually
once per month - who knows, maybe a spike in a grid, sudden cpu usage or
something similar caused it.
Anyway - bigger power supply solved the problem.
