It seems like IRQ delivery didn't work probably due to screaming IRQ. I need to see the messages before the first relevant error message. It's always a good idea to post full kernel log from boot till failure. Things which don't seem relevant are often relevant. >> Move half of the drives to the new PSU and see whether the problem goes >> away. > > This is a new server, with a Chieftec GPS650AB, 650W PSU in it. > Though AFAIK a harddisk consumes around 10W, and I will try to use > more than one PSU-s. I've recently tracked down IO problems a server product line from a major (really, one of the top three) vendor to malfunctioning PSU, so don't trust the labeling too much. > The main problem is that I can't immediately see if it helps or not. > Even if it will work without this problem for a week, I can't be sure it > still will in 2 months... > Because of this - and because I believe that this problem related to the HW > (motherboard, chipset) - I'd rather just throw away the MB and use an > other one with two extra 4 port SATA cards. Till now, none of this kind of problem has been tracked down to MB or the controller while 90% of hardware problems turned out to be power related.
