FreeBSD hangs while booting with USB legacy support off

[Norihiko Murase]

Hi,

My name is Norihiko Murase. I would like you to give me the
comments/suggestions about the symptom described below.


When I started the FreeBSD installation system via DVD
(FreeBSD-***-RELEASE-i386-dvd1.iso), the system hangs while
the devices are being probed.

The last lines displayed was the following::
  pci4: <ACPI PCI bus> on pcib4
  pci4: domain=0, physical bus=4

Curiously, the system does NOT hang at all if the bios
setting of the box is changed as follows:
  <USB Legacy Function> = "Enabled" (from "Disabled")
# opposite to PR#91906 ?!
# http://www.freebsd.org/cgi/query-pr.cgi?pr=91906

After I change the bios setting as described above, the
following lines are displayed::
  pci4: <ACPI PCI bus> on pcib4
  pci4: domain=0, physical bus=4
  found-> vendor=0x1033, dev=0x0194, revid=0x03
          domain=0, bus=4, slot=0, func=0
          class=0c-03-30, hdrtype=0x00, mfdev=0
          cmdreg=0x0006, statreg=0x0010, cachelnsz=16 (dwords)
          lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns)
          intpin=a, irq=12
          powerspec 3  supports D0 D3  current D0
          MSI supports 8 messages, 64 bit
          MSI-X supports 8 messages in map 0x10
          map[10]: type Memory, range 64, base 0xfbcfe000, size 13, enabled
  pcib4: requested memory range 0xfbcfe000-0xfbcfffff: good
  pcib4: matched entry for 4.0.INTA
  pcib4: slot 0 INTA hardwired to IRQ 18
  pci4: <serial bus, USB> at device 0.0 (no driver attached)


Detail of the environment under which I tried is as follows:
  * OS: FreeBSD
      6.4-RELEASE
      7.3-RELEASE
      8.1-RELEASE
  * Motherboard: GIGABYTE GA-P55A-UD5
