Kernel 2.6.27: Problems with DVD drive/nVidia MCP51

After upgrading from 2.6.26.5 to 2.6.27.4, my DVD drive started having problems during boot time. Here is the relevant part from dmesg:

ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: ATAPI: HL-DT-ST DVD+/-RW GSA-T11N, A103, max UDMA/33 ata2.00: applying bridge limits
ata2.00: Drive reports diagnostics failure. This may indicate a drive ata2.00: fault or invalid emulation. Contact drive vendor for information. ata2.00: configured for UDMA/33

ata2.00: status: { DRDY }
ata2: hard resetting link
[continue ad inifitum....]

The drive is reported as "HL-DT-ST DVD+/-RW GSA-T11N, A103", connected to an nVidia MCP51 controller. Googling around, I found similar complaints in the past for other nVidia controllers using the sata_nv driver (though I couldn't find anything about the MCP51). I tried compiling the version of sata_nv that comes with 2.6.26.5, but that did not solve my problems.

I can provide further details if necessary.

Does 2.6.27.5 make any difference?
