no /dev/sr0 (DVD/CDROM) detected after resume from suspension

brobr · 03-04-2013, 04:20 AM

Hi,

I use suspend a lot, but whenever I resume from this, I cannot burn/play DVDs anymore. I have to reboot in order to get the drive recognised. Have I missed something in setting up 'resume from suspend'? I did refresh the /etc/udev/rules.d/*.rules as suggested for the latest udev-upgrade. This 'problem' has been going on, I think, since kernel 3..., so might not be related to the current/14.0 release I am running.

Thanks in advance for any tip that helps me to prevent such rebooting,

Rob

ATA2/sr0 is the DVD-drive.
Can someone give me an idea how this can be solved. I cannot burn an installation DVD at the moment and PXE-booting gives me a headache, but that is another post.....

Cheers,
