I've compiled kernel 2.6.26 and it's working. The all_generic_ide=1 isn't needed anymore, because the kernel switches to UDMA/33 when it detects that UDMA/66 can't be used.
The interesting part from dmesg: [ 9.001603] ata2.01: ATAPI: ASUS DVD-ROM DVD-E616P 0104, E1.04, max UDMA/66 [ 9.001621] ata2.01: limited to UDMA/33 due to 40-wire cable [ 9.017417] ata2.01: configured for UDMA/33 The kernel was configured by using make oldconfig of the config-2.6.24-19-generic config and just entering through all questions. I've attached dmesg and hdparm ouput. ** Attachment added: "kernel-2.6.26.log" http://launchpadlibrarian.net/16212061/kernel-2.6.26.log -- DVD writer not working since hardy upgrade https://bugs.launchpad.net/bugs/228624 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
