This is a post-2.6.27 regression. Panic!

I get this block of messages about every 20 seconds for as long as I'm
booted into a .28 kernel.
It seems that the sata link is being soft reseted about every _20_ secs.
My drive is a sata drive that should be using UDMA/133 (right?),
but the "error" message says configuring for UDMA/33.
Does this mean that my drive is running at a slower speed?
Should I be worried about the .28 kernel corrupting my hardware? Is this
a known issue?
How can I stop it from filling my logs!

What driver in use? ata_piix? Can you give full dmesg (boot + first
few errors)?
Are there any ATAPI devices attached to this controller, in addition to
the Seagate ST980811AS ?
