I'm easily able to reproduce this problem on my sata_promise test rig.
Using 2.6.23-rc5 to dd read a single Seagate disk on a SATA300 TX4 card
quickly fails as Peter described.
Applying the 1.5Gbps patch to the driver appears to make things stable.
Those SATAII chips really don't seem to like 3Gbps mode. Or else we're
missing some critical documentation on how to make them work.
The funny thing is: I have the exact same adapter and disks in a Dell
PE1800 server. This doesn't show any errors.
Only difference is the card is in a PCI-X slot and the server is running
Linux 2.6.19.5.
dmesg from that box:

I'll try to test as Mikael suggested.
