rihad, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Description changed: I have two identical disks set up in a fake RAID configuration through the PC BIOS, over which a LVM2 volume where all my partitions live except /boot, which is on its dedicated RAID partition. After the upgrade to 11.04, when doing a cold restart, /dev/dm-* files aren't found, so the booting halts with an error. Stock 11.04 kernel is used as per uname: Linux rihad 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Apparently the new kernel also messes up the RAID configuration, because the array members are then shown as OFFLINE in the BIOS making the disks unusable, and nothing short of a cold restart brings them back to life. - Fortunately I was wise enough to have saved the previous distro's kernel vmlinuz-2.6.35-28-generic in my GRUB menu, booting into which can correctly initialize the LVM2/DM subsystem, and then after doing a warm reboot into the newer kernel everything works. So I must do a two-phased boot every morning, which sucks. - --- + Fortunately I was wise enough to have saved the previous distro's kernel + vmlinuz-2.6.35-28-generic in my GRUB menu, booting into which can + correctly initialize the LVM2/DM subsystem, and then after doing a warm + reboot into the newer kernel everything works.
