Further details:
The ATA drive in questions is:
ad0: 114473MB <WDC WD1200JB-00DUA3> [232581/16/63] at ata0-master PIO4
The PIO4 comes from booting with 'hw.ata.ata_dma=3D"0"'; it would otherwise=
be
"UDMA66".
Basically, if I use atacontrol to set that channel to WDMA2 or below, then I
get no errors (but performance is awful). At UDMA2 I been to see "TIMEOUT -
WRITE_DMA" and "TIMEOUT - READ_DMA" messages, but the system recovers. At
UDMA4 and above, the kernel panics.
