Ok I did some additional debugging. update-initramfs -u -k 3.10.0-3-generic: 3.10.0-3 still boots fine, so update-initramfs doesn't break it.
update-initramfs -u -k 3.10.0-4-generic: Neither does it fix the problem on -4 kernel boot arguments: The defaults are: linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash modeset=1 pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 $vt_handoff When changing it to: linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash $vt_handoff the -4 kernel boots fine ... What I also noticed it the following error: [ 23.139890] kvm_intel: Unknown parameter `nested' This does NOT happen on -3 kernel. So it seems like modprobe or so is broken for -4 kernel?! -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1203211 Title: Kernel 3.10.0-4 fails on graphical boot with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/1203211/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
