IDE disk initialization problem with tonight's kernel.

Sometime between this morning's cvsup at around 12:00 noon GMT Sunday
and tonight's cvsup at 03:00 GMT Monday some changes were made in the
kernel which caused these errors:


ad0: 76319MB <WDC WD800JB-00CRA1> [155061/16/63] at ata0-master UDMA33
ad1: 76319MB <ST380021A> [155061/16/63] at ata0-slave UDMA33
acd0: CDROM <LTN301> at ata1-master PIO4
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <IOMEGA ZIP 100 90.J> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 96MB (196608 512 byte sectors: 64H 32S/T 96C)
Mounting root from ufs:/dev/ad0s3a
ad0: UDMA ICRC error cmd=write fsbn 281961420 of 140980710-140980713
  retrying
ad0: UDMA ICRC error cmd=write fsbn 281961420 of 140980710-140980713

ad0: UDMA ICRC error cmd=write fsbn 281961420 of 140980710-140980713
  retrying
ad0: UDMA ICRC error cmd=write fsbn 281961420 of 140980710-140980713
  falling back to PIO mode

Note that ad0 and ad1 are both wrongly identified as UDMA33 devices
when they are really UDMA100.  Switching back to this morning's
kernel eliminates the errors, so it seems not to be bad hardware:

ad0: 76319MB <WDC WD800JB-00CRA1> [155061/16/63] at ata0-master UDMA100
ad1: 76319MB <ST380021A> [155061/16/63] at ata0-slave UDMA100
acd0: CDROM <LTN301> at ata1-master PIO4
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <IOMEGA ZIP 100 90.J> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 96MB (196608 512 byte sectors: 64H 32S/T 96C)

This machine has an ASUS A7V8X motherboard which does have an
(unused) SATA controller built in:
atapci0: <Promise PDC20376 UDMA133 controller>
and I'm wondering if Søren's changes to the ata code could be
confusing my motherboard ;-)
