This is a me-too report:

After upgrading a 6-CURRENT kernel and world from 2004.09.09.08.00.00 to
2004.09.16.13.00.00, I am now getting these messages on a machine that
previously worked just fine:

ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=75822564
ad0: WARNING - READ_DMA no interrupt but good status
ad12: TIMEOUT - READ_DMA retrying (2 retries left) LBA=107702399

I only get the messages when I blast the discs with I/O, like when doing
fsck on all the file systems simultaneously. Also, fsck does not report any
problems so all operations seem to succeed.

Other then cvsup'ing the new sources, no other changes were made to the
machine or the configuration.
