Well, same (kernel-panic with hw.ata.tags="1") for me:
...
atapci0: <VIA 82C686 ATA100 controller> port 0xd000-0xd00f at device \
7.1 on pci0
atapci0: Correcting VIA config for southbridge data corruption bug
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
...
ad0: 43979MB <IBM-DTLA-307045> [89355/16/63] at ata0-master UDMA100
I fired up 'gdb' according to the developers handbook on the
