Comment 58 for bug 554737

I have the identical problem on a Dell Inspiron Mini 10v running Lucid with latest updates. Currently I'm getting round the problem using GRUB_CMDLINE_LINUX="noapic, nolapic, noacpi" in /etc/default/grub followed by sudo update-grub. I don't really understand why or how this is working or what consequences it might have: but it seems to work!
