NetBSD alpha crashes into ddb with Delock 81940 multifunction PCI card (USB, 
SATA/IDE controllers) installed on Microway Screamer 400 (DEC AlphaPC 164 
clone). It has VIA VT6214L (USB controller) and VIA VT6421A (SATA/IDE 
controller) chips. I used it on 5.1.x release (including 5.1.2) and netbsd 
"current" at the end of 2011. Because of this I can't tell when it broke. I can 
confirm that this problem still exists on current netbsd-6 branch. The only 
caveat that 5.1 version didn't configure USB controller at all but NetBSD still 
booted successfully:
