I need to do a make world but my system and kernel are only about 2 weeks 
old.  I booted into NT on the same box and was able to close the disks 
using Easy CD creator and the same CDRW drive.  Still, I'm interested in 
solving the "Input/output error" problem.

Looking at the code in atapi-cd.c and atapi-all.c, it seems like the
queued request is getting an EIO.  Judging from the behavior when I tried
to close a session that was already finished, I can only guess that what
the ata driver is sending my drive is different than its expectation for a
close disk command.  Perhaps the track (ccb[5] = 0) in acd_close_disk() is
incorrect for my drive?  It may be non-standard; I'm not an ata expert by
any means.  It returns an error immediately without spinning up the disk
so I assume it's a firmware error.  If there are no further suggestions,
I'll trace into it with ddb and ATAPI_DEBUG. 

Second, it seems that the "out of sequence" stuff is still in -current.  
Is that bound to be removed soon?  It is perfectly acceptable to insert 
media with sessions written a previous time and close the disk without 
writing another session first.
