>Description:
If you use a command (such as mount) reading the ATAPI-CDROM device (eg /dev/acd0a) and the drive is still initializing the drive, the command will fail with a "device busy" message. This patch corrects the problem by making the command waiting for the drive to be ready.
>How-To-Repeat:
-
>Fix:
apply this patch to your (4.2-RELEASE) kernel source tree : (when you are in /usr/src/sys)

** end **
note that since i don't own a scsi cdrom drive, i don't know if this works with it.
note2: since i can't have cvs access, i can't patch directly with the current branch and the patch should work only with the src from 4.2-release.
