Since -pre8 (I have not tried -pre7; but -pre6 works well) the kernel
throws an oops while initializing the SCSI controller:

---------------------------
The oops is reproducible and occurs at any boot.

Footnotes:
[1] Happens in -pre6 also, but without the oops; it is originated
somewhere in dc390_initAdapter() (starts at c0217f40)
