>Description:
  the 5.x kernel from Install CD-ROM probing PnP ISA
devices incorrectly, then hang up.

  belows are dying message on "boot -v" option.

vt0: not probed (disabled)
isa_probe_children: probing PnP devices
adv1: Invalid baseport of 0x220 specified. Nearest valid baseport is 0x230.  Fai
ling probe.
unknown: <Sound Blaster 16> failed to probe at port 0x380-0x38f,0x220-0x22f irq 
5 drq 5,1 on isa0
adv1: Invalid baseport of 0x201 specified. Nearest valid baseport is 0x210.  Fai
ling probe.
unknown: <Game Port> failed to probe at port 0x201 on isa0
 ->>HANG HERE<<-

 but unfortunately FreeBSD 4.x and RHL9 can boot up
with no error.

>How-To-Repeat:

  FreeBSD 5.2-RELEASE, 5.2.1-RELEASE, 5.3-RELEASE are
hanging samely.  some possible boot prompt options
like "set hint...", "unload", etc...  can not make any
workarounds.

>Fix:

  i have no idea, but kernel wizard could fix it.
