I recently obtained an external SCSI CDROM drive that I've hooked up
to my Sparc-II. The kernel sees it ok (I think) but when I mount it I get
"Check Condition on CDB" error, the meaning of which I haven`t a clue. The 
drive seems to mount ok otherwise, the FS is browsable, and 'umount' doesn't
produce an errors. Any ideas whats going on here? I've included a script of
a mount session plus a bit of 'dmesg' output.
