System unresponsive during IDE access


Hello,

I am having a problem with my machine. During periods of even small amounts of disk (or DVD burner) activity, the system becomes totally unresponsive -- the machine doubles as a server, so this is a bit of a problem.

For example, while burning a DVD (at 2X), it is virtually impossible to do anything else on the machine -- from the console, through a shell, or elsewhere. The system responds very slowly.

CPU usage is nowhere near high, and DMA is enabled for both devices. The hard drive is on /dev/hda, and the DVD burner is on /dev/hdd. (hdparm confirms it)

Any ideas?

EDIT: Some info:

$ /sbin/lspci

CPU usage is not a problem. Any sort of disk access makes the system virtually unusuable. Updating slocate's database (via updatedb) is one example of a program that triggers massive unresponsiveness. CPU usage for it is about 2% to 5% on my machine.
