pirx67, 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 . 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 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. As well, please comment on which kernel version specifically you tested. 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', and comment as to why specifically you were unable to test it. Please let us know your results. Thanks in advance. ** Description changed: I'm trying to test the Lucid Lynx Alpha 3 version. When booting the kernel modesetting that is tried in the radeon module leads to a NULL pointer dereference. This affects later also the Xorg process. After some time the boot stalls. No tty console, no Xorg, gdm etc. The system is then dead. No reaction on CTRL-ALT-DEL keys. I managed to log the kernel output by setting the console to /dev/ttyS0 and log the output on another computer. See the attached file lucid_a3_boot.txt. - The apport bug report was created after a successful boot with kernel - modesetting disabled (nomodeset on the boot chooser screen). - - I hope the gathered information is enough. If not please contact me. + WORKAROUND: + The apport bug report was created after a successful boot with kernel modesetting disabled (nomodeset on the boot chooser screen).
