Bug is fixed in 2.6.23.1: sata_promise: port is slow to respond, reset failed

[Peter Favrholdt <linux-ide@how.dk>]

Hi,

The problem is solved in 2.6.23.1 regarding the "port slow to respond" 
issue.

I'm using sata_promise on Promise Technology, Inc. PDC40718 (SATA 300 
TX4) (rev 02) and 4 Seagate 500GB ES drives.

Using 2.6.23.1 it is possible to run

dd if=/dev/sda of=/dev/null bs=1M &
dd if=/dev/sdb of=/dev/null bs=1M &
dd if=/dev/sdc of=/dev/null bs=1M &
dd if=/dev/sdd of=/dev/null bs=1M &

And it just runs perfectly to the end with no hickups :-)

Thank you very much :-)

Best regards,

Peter
