We recently had a problem with the 2.6.38 kernel which was similar, and it was tracked down to being a patch that had been backported from the latest kernel. That patch is in the 3.0.0 kernel. The problem only showed up in systems with hybrid graphics - i.e. both an intel graphics device and another brand of graphics interface.
Before we start bisecting to find the problem, I thought it would be worth reverting that single patch to see if it resolves the issue. Please test that kernel and report whether is solves the problem. The test kernels are here: http://people.canonical.com/~sconklin/lp880476/ And the source tree the kernel is built from is here: http://kernel.ubuntu.com/git?p=sconklin/ubuntu-oneiric.git;a=summary in the branch lp880476 Thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880476 Title: after update to kernel 3.0.0-13 ubuntu 11.10 does not start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/880476/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
