Are you sure that this 'Device busy' did not occur during the sense
period, while the drive itself was trying to find out what kind of disc
you had just popped in? Wait a few seconds (usually until the light
on the drive stops blinking) and try mounting it again.
G'luck,

Of course, I tied to mount after the driver stops blinking.
And I had 'Device busy' message immediately and drive did not even blinked.
I've just reproduced this here. My system is now 4.4-STABLE of 24 November
2001.

Not sure I understand you. CD is not mounted in this example,
there is nothing to unmount. If you insist to run 'umount -f' brefore
mounting,
I tried this. Obviously, this doesn't help.
