Bug Description

After running some upgrades under Ubuntu 11.10, my Asus UL20FT laptop would not boot. It's a dual-boot setup, so the Grub sreen appeared automatically, but after selecting linux 3.0.0-15, it diplayed only a dark screen. I'm reporting this as a plymouth bug in accordance with the instructions here (https://wiki.ubuntu.com/Bugs/FindRightPackage), since I was able to boot in recovery mode

Strategies tried:
- Robooting with recovery mode, machine booted with some issues like low screen resolution
- Rebooting and selecting version 3.0.0-14 from previous versions, machine booted and worked properly
- Re-installed linux 3.0.0-15 packages, machine still would not boot 3.0.0-15
- Removed 3.0.0-15 packages with synaptic, now machine boots 3.0.0-14 by default and works properly

I notice that 3.0.0-15 is no longer showing up as an update for me. I'm aware of a similar thread here (http://ubuntuforums.org/showthread.php?p=11629620), although that person had some success by re-installing the package.

Hi Andrew,

Sounds like a kernel regression. Reassigning to the linux package.

Thanks for mentioning this - let me see what I can do to improve those directions :-)

Hi, can you enable -proposed and update/boot to kernel 3.0.0-16.28, and report the results here? Probably you hit a bug which is fixed there. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I have tried updating to 3.0.0-16 from the proposed repository. Unfortunately the machine would not boot with that kernel either.

Ok, can you follow the "Boot Options" instructions from https://wiki.ubuntu.com/DebuggingKernelBoot and capture the messages? May be that will help pointing the cause of the boot failure.

Might be bug 925350 - could you try booting with i915.lvds_use_ssc=0 on the command line (comment #35 in that bug)?

Thanks for the suggestion, Julian! The proposed kernel boots fine with the i915 parameter set. I'm seeing:

$ more /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.0.0-17-generic root=UUID=7c6d73e4-e301-4ad9-8509-533449b932e7 ro quiet splash vt.handoff=7 i915.lvds_use_ssc=0

As I understand it from that bug, this will be fixed in 3.0.0.18, then.

So this should be the same as bug 925350. The fix indeed is to be released with the 3.0.0-18.31 kernel, still in process to go to -proposed/-updates. Marking as duplicate of 925350.
