Colin Thanks very much for all the info. I had a look into my BIOS version, saw that it was A01 and A08 is available. I excitedly upgraded but it's not fixed this problem :(
I know absolutely nothing about DSDT so I am going to leave the acpi=noirq on my menu.lst for now, I need my laptop working for Launchpad development :) I still consider this a kernel bug because: a) It happened under gutsy but was controlled by blacklisting yenta_socket. This workaround no longer works for hardy and the problem is in fact a lot worse. b) The "broken" DSDT doesn't cause problems when Vista is booted on the same laptop. Yeah I know - as much as I tried to convince Dell to give me a bare laptop they wouldn't :) Cheers -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
