>From the first mail:

hda: max request size: 128KiB
hda: 40021632 sectors (20491 MB) w/2048KiB Cache, CHS=39704/16/63
hda: cache flushes not supported
 hda: hda1 hda2 hda4

It seems that DMA is not used by default (CONFIG_IDEDMA_PCI_AUTO=n),
so this is probably exactly the same issue.

Please try the patch attached to the bugzilla bug entry.

Thanks,
Bart
