In a way I'm glad that I'm not the only one :).. Yes I did cvsup to 2.2-STABLE around that time as well. I'm using a Mitsumi 8x, but I assume it's the same... is that a SCSI cd-writer? if so, we may have differnt problems. I've cc'ed this to freebsd-bugs and freebsd-hackers. If you need any other info (please check through the rest of the quoted material), pleaese let me know...
