definitely my Tyan S3992-E based box I didn't touch since a while, has
difficulties with recent code; this time I wanted to cross-install from
it on a USB-stick and noticed it didn't work. From dmesg :

ohci early: SMM active, request owner change
found-> vendor=0x1166, dev=0x0223, revid=0x01
        domain=0, bus=0, slot=3, func=1

pcib0: slot 3 INTA hardwired to IRQ 10

ohci early: SMM active, request owner change

[same on -current and -8-stable]

I compiled and ran a 7-stable kernel of Oct6-sources (last time I cvs
updated ...) on it, which gives :

ohci0: <OHCI (generic) USB controller> port 0xd400-0xd4ff mem

uhub0: <(0x1166) OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on

Pleasure to provide more info and/or test suggestions.

Merci, Arno
