Re: ahc driver now borked in -current?

Jordan,

I have seen something similar on one of my systems just a few days ago. 
ACPI turned out to be the culprit. It would boot with it disabled, and 
wouldn't with until I upgraded the BIOS.

Since you have all of this "vintage" hardware around, you still have one 
of those pesky 3.5" floppy drives, right? ;-)

Regards,
Andy
