Per my other email -- did you try the legacy IDE driver
instead of libata? Can you provide a boot log from that for Tejun?

Hi Mark,
The device is a Nexcom NSA1083 appliance:
http://www.nexcom.com/product/productshow.jsp?iid=13pid=878
It's an OEM appliance that uses the Intel 965 chipset. We use it as one of
three platforms for our access control and compliance products as it has 8
built in
I'm betting that the SATA/PATA converter is getting confused with
the ata_piix driver's attempt to use MDMA2 on it.
PIO appears to be working fine -- the BIOS uses it to boot,
and libata uses it to do the IDENTIFY operation.
So, try this hack, which should force ata_piix to use only PIO

Yes!! It worked.. which means you were right - forcing the channel to PIO4

have a SATA HDD connected to the same controller used for database and

The best mdma2 can do is the same throughput as pio4,
and the bus occupancy is so high

You can certainly also thank Tejun and Jeff,
for making libata so easy to tune with a one-liner liner like this!

Too true.. thanks Tejun, Jeff and Alan also.. much

Perhaps you two could compare notes ?
Do you have a spare device you can send
