	This is an unexpected disconnect. 
	Did you eject the CD while the drive was active ?
No
	
	
	Please let me know, what kind of CDROM drive you 
	are using (best if you send me a boot message log).
	
	And please give more information about the exact
	situation that caused this problem: How was the 
	CDROM used, how was the eject initiated ?

It is CD-R, but with previous FreeBSD SNAP it works fine. I don't know
what was the reason for errors - new SNAP or second NCR I added just
before new SNAP install.
I try "eject" from various programs (workman,xcd,etc) including cdcontrol.
I use this CD-R as CD with MSDOS,Win95 and WinNT - work good.
Below is boot message log:
