Note: these look like

hdb: dma_intr: status=0x41 { DriveReady Error }
hdb: dma_intr: error=0x44 { DriveStatusError UncorrectableError }, LBAsect=1189689234687, sector=70911
ide: failed opcode was: unknown
end_request: I/O/error, dev hdb sector 70911
Buffer I/O error on device hdb1, logical block 8856
lost page write due to I/O error on hdb1
etc.

So it seems the error is properly reported up to the filesystem
((70911-63) * 512 / 4096 == 8856)
