Same problem on my asus laptop A6T. My DVD Writer is /dev/hda and I got the same messages and also hald-addon-storage eating all CPU.
Checked all my logs on /var/log but didn't find anything before the first "hda status timeout" message which might have caused this. I suspect sata_nv but didn't try yet to disable adma -- Feisty freeze, kernel (?) tries to access DVD drive https://launchpad.net/bugs/75295 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
