Okay, with DMA on hdc disabled shortly after boot I've now seen some of the IDE errors happen without crashing the box. That's nice, but these are still new in Dapper as far as I know. The drive seemed to work fine (in DMA mode) in Breezy.
I'm loathe to move to a different kernel, because this one is the only kernel I've seen so far that does both suspend and hibernate correctly on this machine! But not being able to use my CD drive in UDMA mode renders it basically useless. Well, hope this helps somehow. ** Attachment added: "dmesg log with IDE errors (no DMA, no hang)" http://librarian.launchpad.net/4921001/hdc-errors.txt -- 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
