Hi, I realize this thread is bigger than an encyclopedia by now, so I apologize if this has already been suggested. :) I'm curious if you look at /proc/interrupts if the disk with I/O problems is sharing interrupt with some other device. Maybe there is a conflict of some sort. On my motherboard, one of the SATA controllers shares an interrupt with the soundcard, for example.
