Reproduced on the same hardware, HP nc6400, also running amd64 kernel. System would not boot after upgrade.
Resolved by rolling back to Linux 3.4.17, using the following packages: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.17-quantal/linux-headers-3.4.17-030417-generic_3.4.17-030417.201210311354_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.17-quantal/linux-headers-3.4.17-030417_3.4.17-030417.201210311354_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.17-quantal/linux-image-3.4.17-030417-generic_3.4.17-030417.201210311354_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.17-quantal/linux-image-extra-3.4.17-030417-generic_3.4.17-030417.201210311354_amd64.deb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029790 Title: Can't boot without nomodeset option-kernel 3.5.X.X/3.6.X.X ATI M52 [Mobility Radeon X1300] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
