Something similar here: Acer TravelMate 430 with Lucid 10.04.1 and kernel 2.6.32-24-generic.
The system CPU is "halted" unless I move the mouse or press a key. >From dmesg: [ 8193.108063] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424) [ 8193.108089] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC0.BAT1._BST] (Node ef0182d0), AE_TIME [ 8193.108137] ACPI Exception: AE_TIME, Evaluating _BST (20090903/battery-393) [...] Using acpi=off as a kernel boot option solved the problem for me. I do not have ACPI support anymore but at least I have a working system. Maybe other acpi= options are also valid and less extreme. -- ACPI Error (psparse-0537): Method parse/execution failed https://bugs.launchpad.net/bugs/535643 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
