I'm also sure that this is a bug. My machine with the same hardware worked perfect for 2 years with all past Ubuntu versions. Only this last 2.6.27-6 kernel can't use this hard disk. I normally use this hard disk as secondary SATA drive. If I use only this hard disk as primary SATA drive the system still has the problem. It's not a problem to use one or two hard disk. I think this can help. If I change the jumper in the hard disk from 3GB/s to 1,5GB/s the system runs perfectly. As I tell before the problem is also present in last Debian Lenny kernel.
