System: NetBSD 5.0_BETA (GENERIC) #0: Wed Nov 26 10:23:09 PST 2008  builds@wb27:/home/builds/ab/netbsd-5/macppc/200811260002Z-obj/home/builds/ab/netbsd-5/src/sys/arch/macppc/compile/GENERIC macppc

>Description:
	On my powerbook g4/500 titanium installed with a netbsd-4
	userland (and kernel for normal use) I tried to boot/use an
	actual netbsd-5 kernel (see above) and ran into an hangup
	during booting:

	  [...]
	  pchb2: Apple Computer UniNorth Host-PCI Bridge (rev. 0x00)
	  fwohci0 at pci2 dev 14 function 0: Apple Computer product 0x0018 (rev. 0x01)
	  fwohci0: interrupting at irq 40
	  fwohci0: OHCI version 1.0 (ROM=0)
	  fwohci0: No. of Isochronous channels is 4.
	  fwohci0: EUI64 00:30:65:xx:xx:xx:xx:xx
	  fwohci0: Phy 1394a available S400, 1 ports.
	  fwohci0: Link S400, max_rec 2048 bytes.
	  ieee1394if0 at fwohci0: IEEE1394 bus

	  fwohci0: AR DMA status=8409,  skip buffer done
	  ieee1394if0: 1 nodes, maxhop <= 0, Not found IRM capable node
	  fwohci0: BUS reset

	  uhub1 at usb1: Apple Computer OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
	  [Hangup here!]

	'disable fwohci' with/in userconf(4) avoids this hangup and
	the system boots up normally.

	BTW: At kernel's userconf I tried

	     uc> disable ieee1394if
	     Unknown argument

	     -> Another bug?

	     uc> 'disable fwip'
	     [205] fwip* disabled

	     ... seems to work, but did not prevent the hangup.

	With the netbsd-4 kernel the fwohci output looks like:

	  fwohci0 at pci2 dev 14 function 0: Apple Computer product 0x0018 (rev. 0x01)
	  fwohci0: interrupting at irq 40
	  fwohci0: OHCI version 1.0 (ROM=0)

	  gem0: Ethernet address 00:30:65:xx:xx:xx, 10KB RX fifo, 4KB TX fifo
	  timecounter: Timecounter "clockinterrupt" frequency 100 Hz quality 0

	  resCount=4080 plen=20 len=-4
	  fwohci0: AR DMA status=8409,  skip buffer done
	  fwohci0: node_id=0xc800ffc0, gen=1, CYCLEMASTER mode
	  ieee1394if0: 1 nodes, maxhop <= 0, Not found IRM capable node

	... during a normal/successful boot.

	I do not use the fwohci functionality of my powerbook (yet), I
	just ran into the hangup while trying to boot the netbsd-5
	kernel.

>How-To-Repeat:
	Boot a netbsd-5/5.0_BETA kernel on a powerbook g4/500 titanium
	and see how it hangs up.
>Fix:
	Unknown.
