Since I'm a good little boy, I had a day old dump of my / and /usr partitions (the only thing of interest in the drive). After installing a different hard drive (same model number) and restoring from tape and a 2.2.7 fixit cd I noticed that my system has become very sluggish. Booting in single user mode I notice that top is showing between 8-10% interrupt usage even with no other processes running. This wasn't happening before this reinstall. Does anyone have any ideas of what could be happening? Is it possible to track where all these interrupts are coming from? I've included dmesg output below in case it helps...
