I hooked up a serial console to try to figure it out. Here is what the console displayed. What does this mean? Can it be hardware or is it most likely software?

A few days ago I noticed a "write timeout resetting device" on the ad1 disk. Both IDE drives are on the same controller. This is running FreeBSD 4.10-PRERELEASE #6: Wed May 26 13:23:05 EDT 2004, but was cvsup'd yesterday. The CPU is an AMD Duron 850 with 1.5GB RAM. What should I look to fix on this sytem?
