Hi Jakub, Thank you for taking the time to report this bug and helping to make Ubuntu better.
Also thanks for testing the mainline kernel, it's a good first step, and since you mention your system worked OK with Maverick (kernel 2.6.35), it's probably something that changed between that kernel and the one shipped with Natty (2.6.38). Still, it would be useful to have some more information about your system. To that end, I'd like to ask you to please execute the following command, as it will automatically gather debugging information, in a terminal: apport-collect -p linux 784484 Please do this running the 2.6.38 kernel that the 11.04 system uses by default. Thanks! ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784484 Title: dramatic kernel panic on Ubuntu 11.04 and derivatives- when rebooted. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
