From: David Haggett on 23 Sep 2007 12:54 OK, this is strange. Some DVDs seem to crash my system, while others appear to work perfectly OK. By "work OK" I mean the DVD ROM spins up, and a mounted DVD icon appears on my KDE desktop. When I click on the DVD icon it opens in konqueror and I can navigate through the VOB folders. I can play back (both encrypted and unencrypted) disks through xine using libdvdcss. The other DVDs * Don't spin up properly, but instead make a rattling noise in the drive. * The icon doesn't appear on the desktop. * Load average goes to 2 or higher. * DVD drive refuses to eject (by command or by pressing the button). * X freezes to the extent I can't drop to a console. * Eventually (about 2 - 5 minutes) the whole system freezes and I have to power-reset. Sometimes, a disk will fail to load the first time, but if I can catch it, and issue an eject command, then re-insert the disk it might work. 1 disk in particular refuses to work. Work: Unencrypted magazine cover DVDs. Green Day International SuperVideos Might work Dreamworks Over the Hedge Not Work: AC/DC: Family Jewels (1 and 2) Does this sound like a flaky DVD drive? Or is there something software-wise I can look at? -- David Haggett Linux user since 01/01/2003 Email: david<at>haggett<dot>demon<dot>co<dot>uk

Check dmesg and /var/log/messages to see if there's things like IDE resets being flung about (thats if it's an IDE drive). Also the examples you give don't really mean much, as we don't know what type of disc they are. Try DVDs, CD-ROMs and audio CDs and see if there's any difference. I don't think that putting in an AC/DC disc is likely to cause a problem, the important thing is what type of disc is it, not who owns the copyright ;-) From the sound of it though I reckon your DVD drive isn't very good, the noise from the drive sounds like it's spinning up as fast as it can in an effort to try and make sense of the disc, so check the logs for IDE issues. -- Blast off and strike the evil Bydo empire!

Ah - could this be it? I did a tail -f on /var/log/messages as I put the AD/DC disk in (this time the icon appeared, but there was no content when examined in the file manager.

Well, not sure why a DVD would cause such problems from your DVD drive, you'd think they'd handle it all more sensibly, but the reason it's messing up your system so badly and causing the load to go up is because the IDE controller is throwing a fit, which then means that any hard disc access hangs or fails, so tasks start hanging as they wait for the disc. Try getting a Plextor drive instead, they're a name that's associated with good performance under linux, I've never had any hassles with them. -- Blast off and strike the evil Bydo empire!
