	Seems I didn't try hard enough with the latest version of the code.
At boot I get reams of:

Dec 11 12:05:03 df1 kernel: intr 10 at 40001/40000 hz, livelocked limit
engaged! Dec 11 12:05:04 df1 kernel: intr 10 at 8604/20000 hz, livelock
removed

	With intermittent:

Dec 11 12:05:04 df1 kernel: unknown: FAILURE - INQUIRY timed out

	Early on there are messages like:

Dec 11 11:47:05 df1 kernel: **WARNING** waiting for the following device to
fini sh configuring:
Dec 11 11:47:05 df1 kernel: xpt:        func=0xc0146dd9 arg=0

	After a few of these there is:

Dec 11 11:47:05 df1 kernel: Giving up, interrupt routing is probably hosed

	Eventually however (and this is the bit I didn't wait long enough
for last time round) I get:

Dec 11 12:05:04 df1 kernel: cd0 at ata4 bus 0 target 0 lun 0
Dec 11 12:05:04 df1 kernel: cd0: <TSSTcorp CDDVDW SH-S223F SB00> Removable

Dec 11 12:05:04 df1 kernel: cd1: Attempt to query device size failed: NOT
READY, Medium not present

	The livelock messages go away - and once I reenable DMA on atapi
(it gets turned off somewhere along the line in the boot process)
everything works fine. It just takes 15-20 minutes to get there.

	I'm using an Asus A8V Deluxe motherboard - dmesg | grep ata

	The reuse of ata4 seems odd - related or irrelevant ?
