Hi,

I am getting frequent 'ATA bus error' with ICH7R & WD7500AAKS-0.
I have tried the following combinations of NCQ and Write Cache disabled,
Write I/O is done with dd:
dd if=/dev/zero of=/dev/sdc bs=1048576

(1) With Write Cache is Disabled and NCQ is enabled then the
errors are seen immediately on starting I/O
(2) With Write Cache enabled and NCQ enabled the errors are less frequent
(3) With NCQ disabled using "echo 1 >/sys/block/sdc/device/queue_depth"
the errors are rare but do occur.

I have tried with different SATA Cables & Sata port combinations to
rule out cable/bad port issues.

I am wondering if the WDC WD7500AAKS-0 is another candidate for NCQ blacklist?

These kind of errors are often caused by hardware issues: bad/loose SATA cable, insufficient power supply, etc. When the controller reports things like PHY ready changes, it's not normally a driver problem.
