Christopher, The hangs described in this bug report have been fixed for me. It was, it seems, a RAM hardware issue which my computer store was refusing to aknowledge and blaming Linux for it.
I did however update the BIOS as you suggested, and it seems there are no more ACPI kernel errors as I only get these warnings now, Nov 16 22:42:15 b12 kernel: [ 2.626931] ACPI Warning: 0x0000000000000530-0x000000000000053f SystemIO conflicts with Region \GPR2 1 (20121018/utaddress-251) Nov 16 22:42:15 b12 kernel: [ 2.626937] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver Nov 16 22:42:15 b12 kernel: [ 2.626939] ACPI Warning: 0x0000000000000500-0x000000000000052f SystemIO conflicts with Region \GPR2 1 (20121018/utaddress-251) Nov 16 22:42:15 b12 kernel: [ 2.626943] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/967907 Title: ACPI Error: Method parse/execution To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/967907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
