Ok, just in case it helps anyone. I had a really ugly soft lockup on my desktop. It is running the Feisty release version. The install failed while booting the live disk, as the xserver was unable to start. So I booted the live disk in Safe Graphics Mode and everything worked fine using the standard xorg VESA display driver. Now that I've got a nice Radeon X1600 (RV530LE) PCIe card, I installed the fglrx out of the Feisty apt repository. Everything just standard. But it totally wrecked the machine. Using the fglrx driver I got a soft lockup at starting arbitrary programms. Sometimes even while loading the gnome session itself. To check if it had anything to do with compiz and the nice wobbling windows (that couldn't even be activated) I removed compiz and used the standard metacity window manager. Nothing changed. I still had lockups everytime I started an X session. So finally I suspected the darn fglrx and removed it from the system, reenabling the vesa driver and - rataplan - no lockups ever since:-) Yeehaw! Got my system back. So if anyone is experiencing this really annoying bug, CHECK IF YOU GOT THE FGLRX INSTALLED AND ACTIVATED. IF SO, REMOVE IT AND TRY AGAIN. Anyhow I also noticed it is related to some other drivers as well, but this time it was the fglrx for sure, so give it a try without it.
good luck to all of you having a lockup on your machine greetings sven Output of lspci -v, lsmod, uname -a, cat /proc/cpuinfo; cat /etc/X11/xorg.conf attached in the text file Note: The output of lsmod and xorg.conf are made without the fglrx driver. The way it would look like with the fglrx driver loaded only differs in the vesa driver line in xorg.conf and one line of lsmod output. ** Attachment added: "some hardware and software info about the machine." http://librarian.launchpad.net/7421461/lockup-info.txt -- CPU soft lockup during boot if ipw3945 kill switch is on https://bugs.launchpad.net/bugs/63418 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
