With the patch attached, it won't panic any more.
But still there is parametric problems, getting:

wd0: transfer error, downgrading to Ultra-DMA mode 2
wd0(pciide0:0:1): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)
wd0c: aborted command, interface CRC error reading fsbn 0 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
...
wd0: soft error (corrected)
