Hi Mikael & list,
I have previously reported problems with my setup:
SATA300TX4 + 4 Seagate Barracuda ES 500GB
Just for the record: using the same setup with linux kernel 2.6.25.4
shows the same problem running at 3.0gbps:

Using Mikaels 1.5gbps patch produces no errors doing the same test.

Hi Mikael,
Thanks!
It works perfectly at 1.5Gbps :-)
I think that because it fails at 3Gbps it might eventually fail at
1.5Gbps also... And the error handling was not robust (in my setup with
these drives at 3Gbps).
If I can help investigate further, I'm happy to do that. I have a spare
controller card so I could try swapping them. Do you have any
suggestions for what I should try next?
Best regards,
Peter

No problem. I had intended to drop that patch after 2.6.24-rc8 as it
ought to be obsolete, but then again it might not be. It's available
here:
