It oopses if you try to write on a CDRW without media loaded. Who would do
such a stupid thing ? Me the impatient trying to write before the drive ends
to load the disc...

The bad thing is that it leaves the drive in an ususable state:

Error trying to open /dev/hdc exclusively (Device or resource busy)... retrying in 1 second.
Error trying to open /dev/hdc exclusively (Device or resource busy)... retrying in 1 second.

It does not happen with 2.6.8-rc2. I am not using a pure rc1-mm1, but applied
all the patches neded to build with gcc-3.4.1:

- fix for usb-locking
- sg.c changes to use standard jiffies
- inline corrections from Adrian Bunk for e1000, smp, sunrpc, eth1394.

Yup, nvidia loaded, but does it really matter ?
