Be worth trying clocksource=acpi_pm as well. This works on a server class machine I have and if it does on yours you might find you get fan control etc back.
Of interest would be if you try an 11.04 live CD/DVD and see what happens with your machine. I am suspecting a kernel problem with the 11.04 distro. No matter what I do with acpi kernel options or bios settings I keep getting random kernel panics - trying to assemble some other anecdotal evedience. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/695580 Title: Kernerl 2.6.35-XX fails to boot Asus F81 notebook To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/695580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
