>Description:
sbp not working properly anymore.  After having some load (e.g. ./build.sh), I can't attach my firewire hdd any longer.  This problem occurred after switching from NetBSD-4.0_STABLE to NetBSD-5.0_BETA.  In the -4 series (including 4.0 release) it worked.  Now I get the following message:

fwohci0: BUS reset
fwohci0: node_id=0x8800ffc0, gen=2, non CYCLEMASTER mode
ieee1394if0: 2 nodes, maxhop <= 1, cable IRM = 0 (me)
ieee1394if0: root node is not cycle master capable
ieee1394if0: bus manager 0 (me)
fwohci0: too many cycle lost, no cycle master presents?
ieee1394if0: split transaction timeout: tl=0x1 flag=0x04
send: dst=0x01 tl=0x01 rt=0 tcode=0x4 pri=0x0 src=0x000
fwohci0: BUS reset
fwohci0: txd err= 3 miss Ack err
fwohci0: node_id=0xc800ffc1, gen=3, CYCLEMASTER mode
ieee1394if0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
ieee1394if0: bus manager 1 (me)
fwohci0: txd err= 3 miss Ack err
ieee1394if0: New S400 device ID:01ac912000002684
sbp0 at ieee1394if0: SBP-2/SCSI over IEEE1394
scsibus1 at sbp0: 1 target, 0 luns per target
sbp_attach: cannot create dmamap
ocb shortage!!!

If I do fwctl -r fw0 a few times or remove and reinsert the device the box freezes.  No ddb or kernel dump.

The controller is the following:
fwohci0 at pci2 dev 5 function 0: vendor 0x1106 product 0x3044 (rev. 0x46)
fwohci0: interrupting at ioapic0 pin 20
fwohci0: OHCI version 1.0 (ROM=1)
fwohci0: No. of Isochronous channels is 4.
fwohci0: EUI64 00:0a:48:00:00:00:04:5e
fwohci0: Phy 1394a available S400, 3 ports.
fwohci0: Link S400, max_rec 2048 bytes.
(some VIA chipset)

I run it on the ASUS AM2-VM motherboard with the latest BIOS upgrade just in case there are any ACPI or other problems which don't show up on -4.  As mentioned before, on -4 I don't get such problems.
