I have seen the very same problem on two different laptops, both with dual VGA configs (Intel and Radeon, Intels are 8086:0106 and 8086:0166 respectively, Radeon is 1002:6840 in both cases). 3.5.0-26 works, 3.5.0-27 doesn't.
One laptop allows for disabling the Radeon in the BIOS - 3.5.0-27 works fine then. Clearly the problem is related with dual VGAs. Back to dual VGA in BIOS, I tried the two bisection kernels - same as others reported already, bisect01 works, bisect02 does not. All this is with the amd64 kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167114 Title: Ubuntu Kernel 3.5.0-27 does not boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
