FreeBSD 6.2-RC2 installation hangup with USB keyboard

[Alexander Pohoyda]

Hello!

I've got a new PC (Shuttle XPC SS21T with SiS 761GX+966L chipset)
which hangs up while booting from the installation CD.

Here's what I get (typed by hands):

pci0: <multimedia, audio> at device 2.7 (no driver attached)
ohci0: <SiS 5571 USB controller> mem 0xfbfff000-0xfbffffff  irq 20 at device 3.0 on pci0
ohci0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xfbfff000
ohci0: [GIANT-LOCKED]
usb0: OHCI version 1.0, legacy support
usb0: SMM does not respond, resetting
usb0: <SiS 5571 USB controller> on ohci0
usb0: USB revision 1.0
uhub0: SiS OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 4 ports with 4 removable, self powered
ohci1: <SiS 5571 USB controller> mem 0xfbffe000-0xfbffefff  irq 21 at device 3.1 on pci0
ohci1: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xfbffe000
ohci1: [GIANT-LOCKED]
usb1: OHCI version 1.0, legacy support
<<<dead locked here>>>


The keyboard is a normal HP USB keyboard, detected by FreeBSD 4.9 as:

ukbd0: Compaq USB Keyboard, rev 1.10/1.00, addr 2, iclass 3/1
kbd1 at ukbd0
uhid0: Compaq USB Keyboard, rev 1.10/1.00, addr 2, iclass 3/0


BTW, FreeBSD 6.0 and 5.4 (i386) installations also hangs up at the
very same place and OpenBSD 4.0 (amd64) installation hangs up with
this output:

ohci0 at pci0 dev 3 function 0 "SiS 5597/5598 USB" rev 0x0f:  irq 11, version 1.0, legacy support
usb0 at ohci0: USB revision 1.0
uhub0 at usb0
uhub0: SiS OHCI root hub, rev 1.00/1.00, addr 1
uhub0: 4 ports with 4 removable, self powered
ohci0 at pci0 dev 3 function 0 "SiS 5597/5598 USB" rev 0x0f:  irq 6, version 1.0, legacy support


Is there a way around this problem?
