Hi,

I have a machine that sometimes gets into a state where it doesn't stop
spitting the following message on the console:

siside0:0: unable to load xfer table DMA map for drive 0, error=3D22
wd0g: DMA error reading fsbn 8065451336 of 8065451336-8066850000 (wd0 bn 80=
82378743; cn 8018232 tn 14 sn=20
5), retrying

The numbers vary depending on which sector is being accessed, and
eventually I can get a segfault in wdc_ata_bio_intr.

What could be happening?  I'm not convinced the disk has a problem.

Thanks for any insight.
