Comment 3 for bug 126898

I have the same problem. After trying to write a DVD with k3b, I could see the same messages as Achraf in /var/log/messages (except that my DVD+-RW is hdd, not hdc). After that, no DVD - written or blank - is recognized in the unit. So I can't read any DVD, nor I can burn another blank.

It's annoying, as I already started to think to switch Ubuntu to some other distro.

Below is my 'uname -a' output:
Linux acasa-desktop 2.6.20-16-386 #2 Sun Sep 23 19:47:10 UTC 2007 i686 GNU/Linux

Attached are dmesg.log and lspci-vvnn.log. Since the problem happened yesterday, the dmesg.log may not be relevant.
