It happens randomly for all disks on the promise controllers. Never for the system disk on hda (on the motherboard buildin controller). The above was just a random snippet from dmesg, there is alot more of the same spam.

It is a 350W powersupply. I wanted something bigger, but couldn't get it for sane prices. I can't rule out that it is overloaded of course. If it is, I haven't seen any other symptoms, the system is rock stable so far.
