[Bug 969276] Re: 12.04 64bit beta-2 doesnt boot on Lenovo W520


Hans Bayle, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in a
working install from a Terminal (Applications->Accessories->Terminal),
as it will automatically gather and attach updated debug information to
this report:

apport-collect -p linux <replace-with-bug-number>

Also, in your working install, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

  12.04 64bit beta-2 doesnt boot on Lenovo W520

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:

  I installed 12.04 64bit beta-2 successfully on a Lenovo T420, after that 
  I tried to install on a  Lenovo W520.

  This gives problems, a boot with the splash disabled will hang and the 
  last visible message is:

  11.716922 udevd[133]: Starting version 174.

  On the same laptop I previously installed 11.10 and Mint 12 without problems.
  The same Kubuntu 12.04 64bit beta-2 CDROM was used to succesfully install the system on a Lenovo T420.

  To include output from the following commands etc. isn't yet possible
  at this point in the booting process, but I'm open for suggestions to
  provide other kinds of info.
