Hello all,
on my girlfriend's laptop (Acer Aspire 3630 on 2.6.23.12-52.fc7), the DVDRW is not working!!
I can't burn anything and sometimes, even in read mode, the CD stops to work and I have to reboot because the system is too slow.

/var/log/messages says:

It's seems related to this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=243043


I was quite sure that I didn't have this problem before with old kernels (I remember she used the CD burner without any problem)
I really don't know how to do next! :confused:

Thanks
