Something changed with the AHCI SATA driver in the latest git version.
With 2.6.21 I get ~49MB/sec according to hdparm. Using the latest git
version I only get ~8MB/sec. I've attached my .config and have
included some info about my system below. Please let me know if you
need more information or if I can help test anything.

Until we know how widespread this damage is, we'd need to consider this
a blocking bug.

Are you able (as a matter of some urgency) to run a git bisection 
search to identify the offending commit?

Thanks.
