doctordruidphd, 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? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingCasper ?
As well, could you please test for this 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 please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: needs-upstream-testing 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 text: needs-upstream-testing If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Please let us know your results. Thank you for your understanding. ** Tags added: amd64 karmic ** Tags added: regression-release ** Description changed: I cannot boot the 64-bit Live CDs for Karmic ubuntu, xubuntu, or kubuntu. When I attempt to boot, I get the language select screen, then the menu. When I choose either Run... or Install..., it goes immediately to a black screen with cursor in the upper left, and hangs. There is no response to CTRL-ALT-DEL or ALT-SYSRQ-REISUB; it requires powering down by turning off the power switch. The same problem exists with Lucid (which I realize is alpha) cds. The problem also exists with the most recent Sidux live CD (Sidux is another debian-sid distribution, using the 2.6.32 kernel). Note that I CAN boot with an installed karmic (2.6.31) and sidux (2.6.32) 64-bit systems, and with a karmic system upgraded to 2.6.32 kernel. Attempting to upgrade the karmic system to lucid produces a system that fails after the udev warnings, apparently unable to mount the file system. This system is: Dell XPS630i, 64-bit, Intel Q9550 core2dual quad processor, 8gb ram, NVIDIA board, dual NVIDIA 9800GT video cards, no onboard video. What I have done: - Verified MD5SUM of downloads and burns. - Attempted removing the slave video card, does not help. - Tried unplugging one or both hard disks, does not help. - Tried booting off USB with all CD and hard drives unplugged, does not work. - Tried the 32-bit CDs, these do boot though I have not tested them extensively. - No RAID is in use on this system - RAID disabled in BIOS. - Returning BIOS to default settings, does not help. No overclocking or overvoltage in use. - Tried the Alternative CDs, they hang in the same spot. - Tried the available options in F4 and F6, removing "splash", etc, does not help. + Verified MD5SUM of downloads and burns. + Attempted removing the slave video card, does not help. + Tried unplugging one or both hard disks, does not help. + Tried booting off USB with all CD and hard drives unplugged, does not work. + Tried the 32-bit CDs, these do boot though I have not tested them extensively. + No RAID is in use on this system - RAID disabled in BIOS. + Returning BIOS to default settings, does not help.
