f918ec7bac * firewire.c 
- Don't initiate bus reset even if probe failed for some nodes to prevent
	infinite bus reset loop.

Problem Reported by: Pierre Beyssac <pb@fasterix.frmug.org>

- Protect timeout routine with splfw() for 4-stable.

* sbp.c

- Make sure to release devq when start request.

c26f4c7168 Clear the bus reset event flag as soon as possible after 
the initialization has completed to start transactions even when
interrupt is disabled during the boot process.

f3d2847dd0 - Though I got a feedback from the originator of kern/48129 that the 
previous revision fixed the panic, I found the problem exits in
another part of the function by investigating the crom dump sent by him.
The search was started in the middle of bus info block and the
routine misunderstood the EUI64 as a crom entry. This problem is fixed.

PR: kern/48129

Fix incorrect type mask included in a logical unit number and check
the validity of the lun.

627d85fbdd firewire/fwohci 
- Drain fwohci TX queue first then drain xfer queue which has not started.
- Check validity of the received packet length.
- Don't allocate too large buffer for xfer receive buf.

sbp
- Fix panic for some CROM which doesn't have a text leaf.
	This could fix the PR kern/48129 but no feedback has been gotten from
	the originator yet.
- Put back some M_NOWAIT flags into malloc which could be called
	in interrupt context for 4-stable.

48249fe0c8 - Take malloc type as an argument in fw_xfer_alloc(). 
- Fix overwrite problem of freed buffers. It was rare but could happen
	when fwohci_arcv() is called before fwohci_txd() is called for
	the transcation.
- Drain AT queues and pend AR queues on SID receive rather than BUS reset to
	make sure DMA actually stops.
- Do agent reset in sbp_timeout().
