I still can't seem to be able to boot -CURRENT with the ATA driver,
much as I'd like to, due to the `timeout-resetting device' error, which
I've seen more people report. I've sacrificed some dead trees to give
you the exact boot messages:
ad0: <WDC AC22100H/12.07H12> ATA-0 disk at ata0 as master
ad0: 2014MB (4124736 sectors), 4092 cyls, 16 heads, 63 S/T, 512 B/S
ad0: 16 secs/int, 1 depth queue, WDMA2
ad1: <WDC AC22500L/32.41N37> ATA-3 disk at ata0 as slave
ad1: 2441MB (4999680 sectors), 4960 cyls, 16 heads, 63 S/T, 512 B/S
ad1: 16 secs/int, 1 depth queue, UDMA33
.
.
Mounting root from ufs:/dev/ad0s1a
ad0: ad_timeout: lost disk contact - reseting
ata0: resetting devices ..
After which the machine hangs _hard_ (i.e. no respone except to the
reset key).
The information given is mostly correct: The second drive is
UDMA33 and can handle it with the WD driver. Also, when this drive
is removed, the error still occurs.
I'm in doubt as to the first drive though: The BIOS says it's 'Mode 4',
is that the same as WDMA2? Could the harddisk be reporting the wrong
value, even though the BIOS is giving the correct one? I'm just grasping
at straws here.
