kern/103602: drive gets wedged on READ CD CAPACITY if no disc is in

[Josh Carroll]

Now I'm a bit confused. I'm not sure what I need to patch and what has
already been committed to -CURRENT. I couldn't apply the cumulative
patch since it complains about a reverse patch or it already being
applied. Whether that's the entire patch or not, I don't know.

>From what I can tell, I need:

1. cam_xpt.c patch (to work around the serial quirk)
2. scsi_cd.c patch
3. atapi-cam.c patch (which I thought was already committed)

cvsup'ing -CURRENT as of about 10pm PST today and applying patches 1
and 2 mentioned above, I still see an interrupt storm and I see an
acd0 failure for READ CD CAPACITY.

So I may be missing a patch at this point, or something else is awry.
Thomas, am I missing something here? Sorry, after not looking at it
for almost 2 weeks, I don't recall which patches were in place when I
last tested.

Thanks,
Josh
