I can confirm this bug: After upgrading to 8.04, the kernel doesn't recognize one of my hard disks (the one with the root partition on it) any more (a seagate IDE disk). Booting with the old (2.6.22) kernel works fine. It's not recognized by the live CD either. The other disk (also IDE) is displayed alright, all partitions show up correctly in /dev/disk/* as sdd* as expected. The disk without the partition table _does_ show up as a block device as /dev/sdc, though.
Relevant output from lshw (run under 2.6.22) follows: *-ide:1 description: IDE Channel 1 physical id: 1 bus info: [EMAIL PROTECTED] logical name: ide1 clock: 33MHz *-disk:0 description: ATA Disk product: ST3160812A vendor: Seagate physical id: 0 bus info: [EMAIL PROTECTED] logical name: /dev/hdc version: 3.AAJ serial: 4LS440SN size: 149GiB (160GB) capabilities: ata dma lba iordy smart security pm partitioned partitioned:dos configuration: mode=udma2 signature=bbbbbbbb smart=on *-volume:0 description: EXT3 volume vendor: Linux physical id: 1 bus info: [EMAIL PROTECTED],1 logical name: /dev/hdc1 logical name: / logical name: /dev/.static/dev version: 1.0 serial: 9bdd3a49-2483-4c2d-9b4a-6aaf1e089a73 size: 20GiB capacity: 20GiB capabilities: primary bootable journaled extended_attributes large_files huge_files recover ext3 ext2 initialized configuration: created=2008-02-06 19:02:16 filesystem=ext3 modified=2008-04-26 23:25:04 mount.fstype=ext3 mount.options=rw,data=ordered mounted=2008-04-26 23:25:04 state=mounted *-volume:1 description: Linux swap volume physical id: 2 bus info: [EMAIL PROTECTED],2 logical name: /dev/hdc2 version: 1 serial: 1b77acd9-bea4-47fd-b12b-c2bbb12f327d size: 972MiB capacity: 972MiB capabilities: primary nofs swap initialized configuration: filesystem=swap pagesize=4096 *-volume:2 description: EXT3 volume vendor: Linux physical id: 3 bus info: [EMAIL PROTECTED],3 logical name: /dev/hdc3 logical name: /home version: 1.0 serial: bd9da549-79e8-46fb-b08a-8036ae1c11f6 size: 29GiB capacity: 29GiB capabilities: primary journaled extended_attributes large_files huge_files recover ext3 ext2 initialized configuration: created=2008-02-06 19:02:40 filesystem=ext3 modified=2008-04-26 23:26:23 mount.fstype=ext3 mount.options=rw,data=ordered mounted=2008-04-26 23:26:23 state=mounted *-volume:3 description: Windows FAT volume vendor: mkdosfs physical id: 4 bus info: [EMAIL PROTECTED],4 logical name: /dev/hdc4 logical name: /data-neu version: FAT32 serial: 47a9-fbc4 size: 98GiB capacity: 98GiB capabilities: primary fat initialized configuration: FATs=2 filesystem=fat label=dataneu mount.fstype=vfat mount.options=rw,gid=46,fmask=0007,dmask=0007,codepage=cp437,iocharset=iso8859-1,utf8 state=mounted *-disk:1 description: ATA Disk product: IBM-DTLA-307030 vendor: IBM physical id: 1 bus info: [EMAIL PROTECTED] logical name: /dev/hdd version: TX4OA50C serial: YK0YKT2P876 size: 28GiB (30GB) capacity: 28GiB (30GB) capabilities: ata dma lba iordy smart security pm apm partitioned partitioned:dos configuration: apm=off mode=udma2 signature=0a6b0a6a smart=on *-volume:0 description: Windows FAT volume vendor: MSDOS5.0 physical id: 1 bus info: [EMAIL PROTECTED],1 logical name: /dev/hdd1 logical name: /windows version: FAT32 serial: 688d-c6c1 size: 10001MiB capacity: 10001MiB capabilities: primary bootable fat initialized configuration: FATs=2 filesystem=fat mount.fstype=vfat mount.options=rw,gid=46,fmask=0007,dmask=0007,codepage=cp437,iocharset=iso8859-1,utf8 state=mounted *-volume:1 description: Linux swap volume physical id: 2 bus info: [EMAIL PROTECTED],2 logical name: /dev/hdd2 version: 1 serial: 0c94c6f1-d36f-42d4-bb79-5c4a04966d12 size: 368MiB capacity: 368MiB capabilities: primary nofs swap initialized configuration: filesystem=swap pagesize=4096 *-volume:2 description: Windows FAT volume vendor: mkdosfs physical id: 3 bus info: [EMAIL PROTECTED],3 logical name: /dev/hdd3 logical name: /data-alt version: FAT32 serial: 46df-3e0f size: 18GiB capacity: 18GiB capabilities: primary fat initialized configuration: FATs=2 filesystem=fat mount.fstype=vfat mount.options=rw,gid=46,fmask=0007,dmask=0007,codepage=cp437,iocharset=iso8859-1,utf8 state=mounted Please pass this bug over to the kernel team as critical (unable to mount the root file system here), and possibly also upstream. (Don't know if this is fixed in a newer kernel version maybe.) ** Attachment added: "output of lshw, the disk shown as hdc1 causes errors in 2.6.24" http://launchpadlibrarian.net/13949523/lshw_20080426 -- unable to read IDE partition table under 8.0.4 https://bugs.launchpad.net/bugs/221677 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
