I was able to reproduce it on second machine (also SR2520SAXS platform) in ~2
hours of heavy IO with other Samsung hard disks (400GB, previously 320GB). I
also tested WDC WD3200YS-01P 320GB hard disk but the problem didn't occur
here even after 20h of testing.
Looks like it's triggered only with some hard disks. I'm going to test Seagate
disks now.
