Public bug reported:
I updated to 2.6.27-2 today, and one of my hard drives is no longer
recognized. It is in a Vantec NexStar GX enclosure, and was working fine
on .26, and continues to work fine on a Hardy machine. Here is the dmesg
for it:

The 4 port hub that is a part of the enclosure continues to work fine
though, with a floppy drive, a printer, and another hard drive. I have a
Vantec NexStar 3 enclosure as well, and it is working just fine. Dmesg
