[Bug 1050900] Re: Unable to boot without 'noapic' boot flag


Stephen Rees-Carter, as per http://download.lenovo.com/express/ddfm.html
an update is available for your BIOS (1.23). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see

Thank you for your understanding.

  Unable to boot without 'noapic' boot flag

Status in “linux” package in Ubuntu:

Bug description:
  When I try and boot 12.10 from a live CD without any tweaks, it
  crashes on a black screen and requires a hard-reset. The only way to
  get around it is to enable the 'noapic' boot flag.

  This problem has been present for the past couple of releases, and it'd be great if it actually got fixed. I've reported it before, but I've made a new bug report now to provide updated dumps etc.
  It's worth noting that at one point it was actually fixed in the mainline kernels, see comment #7 on Bug #903558.
  I also had some success with a custom kernel config file someone provided me, but I lack the skills to identify the solution from that.

  I'd love to get some help with this bug. Please.
