I just joined the list today so apologies if this email breaks any email client post threading.
I have been seeing similar errors on two different systems. I applied Robert's sata_nv patch posted to the list on May 5th, and approved today by Jeff Garzik. I've taken several steps to insure that this isn't a faulty cable or drive issue. This is running on a hp dl145g2. Here is my lspci, dmesg, and relevant kernel config sections:
