2.0F kernel fail to detect ATA disk on ATA secondary channel.

2.0E kernel reports:
wd2 at atabus1 drive 0: <Maxtor 4R120L0>
wd2: drive supports 16-sector PIO transfers, LBA48 addressing
wd2: 114 GB, 238216 cyl, 16 head, 63 sec, 512 bytes/sect x 240121728 sectors
wd2: 32-bit data port
wd2: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd2(viaide0:1:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA data transfers)

2.0F kernel reports:
wd2 at atabus1 drive 0: <ST506>
wd2: drive supports 1-sector PIO transfers, chs addressing
wd2: 69632 KB, 1024 cyl, 8 head, 17 sec, 512 bytes/sect x 139264 sectors
wd2(viaide0:1:0): using PIO mode 0
viaide0:1:0: wait timed out
wd2d: device timeout reading fsbn 0 (wd2 bn 0; cn 0 tn 0 sn 0), retrying
wd2: soft error (corrected)

This breaks all data on wd2. yes, all...
>How-To-Repeat:
2.0F kernel doesn't detect ATA disk properly.
