System: NetBSD mini.julipedia.org 5.99.49 NetBSD 5.99.49 (GENERIC) #1: Sun Apr 17 08:45:23 IST 2011 builder@mini.julipedia.org:/home/builder/obj/usr/src/sys/arch/macppc/compile/GENERIC macppc
Architecture: powerpc
Machine: macppc
>Description:
	After upgrading my Mac Mini G4 1.2GHz from NetBSD 5.1 to current
	(5.99.49), my Firewire 400 hard disk has stopped working.

        I was tempted to file this as port-macppc but I believe this is a
	generic problem in the driver not really related to the platform.
	(This supposition may be of course wrong.)

	The fwohci driver has suffered several changes since 5.x was
	branched and I presume some of them have broken the driver.

	During the boot process, I see the following relevant messages:

	fwohci0 at pci2 dev 14 function 0: Apple Computer UniNorth Firewire (rev. 0x81)
	fwohci0: interrupting at irq 40
	fwohci0: OHCI version 1.10 (ROM=0)
	fwohci0: No. of Isochronous channels is 8.
	fwohci0: EUI64 00:11:24:ff:fe:76:e8:3e
	fwohci0: Phy 1394a available S400, 2 ports.
	fwohci0: Link S400, max_rec 2048 bytes.
	ieee1394if0 at fwohci0: IEEE1394 bus
	fwip0 at ieee1394if0: IP over IEEE1394

	ieee1394if0: bus manager 1
	[...]
	fwohci0: too many cycle lost, no cycle master present?

        Later on, if I turn off and on the hard disk, I get these:

	fwohci0: BUS reset
	fwohci0: node_id=0xc800ffc0, gen=3, CYCLEMASTER mode

>How-To-Repeat:
	Get a machine with a fw400 port (maybe needs to be a macppc) and plug
	a device.
>Fix:
	Yes please.
