Does toggling:
hw.ata.ata_dma="0"
...in loader.conf make a difference?
I'd imagine you'd like DMA to work but knowing whether the problem goes anyway
with DMA off is useful to test. For that matter, does a careful application
of compressed air to remove any dust or lint inside the drive help?
Also, is this problem specific to -CURRENT or reproducible elsewhere?
