I used dist-upgrade from edgy->feisty. After I edited /etc/fstab manually and replaced /dev/hda* with UUID, the system boots and mounts disks - but there are still no /dev/hda* devices so this breaks hdparm and other things.
On my host I have the following HDDs: /dev/hda, /dev/sda and /dev/sdb. Comparing 'fdisk -l' output on the same host booted single-user mode with 2.6.20-13 and 2.6.20-14 shows that with 2.6.20-14 /dev/hda -> /dev/sdc: {root 13:33:25} diff fdisk-l-13.out fdisk-l-14.out 2,14d1 < Disk /dev/hda: 163.9 GB, 163928604672 bytes < 255 heads, 63 sectors/track, 19929 cylinders < Units = cylinders of 16065 * 512 = 8225280 bytes < < Device Boot Start End Blocks Id System < /dev/hda1 * 1 1958 15727603+ 7 HPFS/NTFS < /dev/hda2 1959 2695 5919952+ 83 Linux < /dev/hda3 2696 3296 4827532+ c W95 FAT32 (LBA) < /dev/hda4 3297 19929 133604572+ f W95 Ext'd (LBA) < /dev/hda5 3297 8395 40957686 7 HPFS/NTFS < /dev/hda6 8396 8518 987966 82 Linux swap / Solaris < /dev/hda7 8519 19929 91658826 83 Linux < 31a19,31 > > Disk /dev/sdc: 163.9 GB, 163928604672 bytes > 255 heads, 63 sectors/track, 19929 cylinders > Units = cylinders of 16065 * 512 = 8225280 bytes > > Device Boot Start End Blocks Id System > /dev/sdc1 * 1 1958 15727603+ 7 HPFS/NTFS > /dev/sdc2 1959 2695 5919952+ 83 Linux > /dev/sdc3 2696 3296 4827532+ c W95 FAT32 (LBA) > /dev/sdc4 3297 19929 133604572+ f W95 Ext'd (LBA) > /dev/sdc5 3297 8395 40957686 7 HPFS/NTFS > /dev/sdc6 8396 8518 987966 82 Linux swap / Solaris > /dev/sdc7 8519 19929 91658826 83 Linux -- Kernel 2.6.20-14 does not boot anymore https://bugs.launchpad.net/bugs/104232 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
