I am also affected by this bug, but found a solution where for several days now booting works, suspend works using 64bit 11.10
all i did was: use "noapic" as Kernel cmdline parameter I have successfully suspended/restarted in the last few days, i am not sure about booting on battery, but this has made the system much more stable for me while keeping acpi working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: [Lenovo W520] laptop freezes on ACPI-related actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
