Subject2.6.11-rc5: sata_sil shows drive twice...
hi,

dmesg shows this:

but I only have one physical drive attached. I don't seem to have problems
though. Yesterday I got an oops, but I don't know whether it is connected. I
copied it here just in case.

I don't know whether rc4 or earlier showed this beahaviour. I am sure that
2.6.10 didn't show it.

If you need more info, just shout...

Here the oops:
