"Me too!" I belive this is a problem in the -current code, as my box has
been running for years with no problems, untill recently. Here is my info:

Sep 13 03:01:11 fbsd kernel: ad0: TIMEOUT - READ_DMA retrying (2 retries
left) LBA=56510247
Sep 13 03:01:11 fbsd kernel: ad0: WARNING - READ_DMA no interrupt but good
status
ep 14 00:05:45 fbsd kernel: ad2: TIMEOUT - READ_DMA retrying (2 retries
left) LBA=94967007
Sep 14 00:06:16 fbsd kernel: ad2: WARNING - removed from configuration

After this i could no longer access ad2, and i had to reboot. The reboot
was unable to fully sync the disks, and ad0 had to be fscked on restart.

I am running: FreeBSD 6.0-CURRENT #0: Thu Sep  9 18:56:56 EDT 2004

On a single amd athlon, asus a7v133 mb. Generic kernel - devices i dont have.
