I just tried to boot a recent 2.5 amd64 kernel. Result is that it is 
hanging at boot during SuSE 8.2 hwscan.

Backtrace points to the new IDE taskfile code:

hwscan        D 0000000000000000 18446744073706259928   861    847                     (NOTLB)

hdc: lost interrupt

Followed by more lost interrupt messages.

Any ideas?
