@Joseph Comment #14 refers to v3.2-rc7 not v3.3-rc7. See comment #7 for more details on the tested versions. I just checked v3.3-rc7 and it is still broken, so it's not fixed.
It appears to be related to the config file, as opposed to the actual kernel code... see comments #10 & #17. The result changed depending on which config file I used to compile the kernel. I was given a custom one for my L520 which works fine with the kernel git, while the Ubuntu default kernel config was causing the issue to happen. My assumption is that there was a change of config defaults when v3.2-rc7, etc, were compiled, compared with the newer kernel builds (i.e. v3.3-rc7). It would be great to find out what this was, and have it reversed if possible? It's also worth nothing that older kernel builds, such as the ones with 11.04 & 11.10 also had this issue. So it was resolved for a couple of kernel builds and then broken again. Does that give you more to work with? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/903558 Title: Unable to boot 12.04 without 'noapic' flag enabled in GRUB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/903558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
