Some more information: I'm trying to see if this will happen after having turned off DMA on the affected device at bootup by running "hdparm -d 0 /dev/hdc". Note that I didn't have these crashes in Breezy, and I was manually enabling DMA for my CD-ROM there. (In 2.6.12 DMA did not come up by default for CD- ROMs on this controller.)
There seems to be no pattern to when it happens, nor is it induced by any user input. I have successfully read and burned DVDs with DMA on without problems. -- Kernel panic with Dapper kernel on Acer Ferrari 4005 (panic attached) https://launchpad.net/bugs/66966 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
