New scsi messages in dmesg with 2.6.17-rc4-mm1 including a slightly worrying "Unexpected busfree while idle"

Hi,
I've been running 2.6.17-rc4-mm1 for a little while, just to test it out a bit.
Haven't been doing anything special, just what I'd be calling normal
desktop use (well, maybe starting a few more apps than usual at the
same time, but nothing special).
After about an hour or so I thought "hmm, better check dmesg to see it
this new kernel has said anything interresting" and indeed it had.
I found these messages in the dmesg output in addition to what I'd
normaly expect :
(scsi0:A:5:0): No or incomplete CDB sent to device.
scsi0: Issued Channel A Bus Reset. 1 SCBs aborted
(scsi0:A:5:0): Unexpected busfree while idle
SEQADDR == 0x16c
(scsi0:A:4:0): No or incomplete CDB sent to device.
scsi0: Issued Channel A Bus Reset. 1 SCBs aborted
I don't recall ever having seen these before with previous kernels, so
I'm wondering what exactely could be causing them...?
I've been trying for the past 20 minutes to run through the same apps
as I had running the previous hour, but I've not been able to provoke
more messages :( So I'm pretty clueless as to the cause. Hopefully
someone can clarify.
A few random details about my system below - not quite sure what would
be relevant, so please just ask for specific details if you need them.

If some fields are empty or look unusual you may have an old version.
