Hello,


My mistake, it looks like the issue is to do with writing only.

Mounting a standard DVD works fine with 2.6.24-rc2-git2.

As soon as I try to use wodim or load k3b, that's when drive gets locked
up.

The issue was still there with 2.6.23-git15 , I will continue to test
with previous ones.


Regards,

Will Trives
