I'm not 100% certain, this is a "legal" thing to do. But I think
it is.
I hooked up a brand new hard-drive (Seagate) to the free SATA port,
and then connected the power cable. Before that I had just one SATA
drive (ad8).
The kernel crashed in ata_identify(). I'll keep the core around for
some time -- let me know, if you need more investigation...
The kernel is 6.2-STABLE #1: Thu Jun 7 22:11:33 EDT 2007 ... amd64
