Just FYI, I'm getting the same ACPI error, but I got two of them and I also got others.
Motherboard: AsRock P4VM890 BIOS: 1.90 (latest) CPU: Pentium 4 3 Ghz (Northwood) (at 800 Mhz FSB) RAM: 2GB in 2 slots (DDR400 underclocked to DDR333) Graphics: NVIDIA Kernel: Linux Gigabob 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux Distribution: Ubuntu Gutsy Gibbon No overclocking or anything. I suspect it might be a faulty BIOS. The specific errors: [ 51.090832] ACPI Warning (tbutils-0217): Incorrect checksum in table [ ð] - 00, should be 6A [20070126] [ 51.091040] ACPI Error (tbinstal-0134): Table has invalid signature [ ð], must be SSDT, PSDT or OEMx [20070126] [ 51.091257] ACPI Error (psparse-0551): Method parse/execution failed [\_PR_.CPU1._PDC] (Node df848180), AE_BAD_SIGNATURE [ 51.192365] ACPI Warning (tbutils-0217): Incorrect checksum in table [ ð] - 00, should be 6A [20070126] [ 51.192572] ACPI Error (tbinstal-0134): Table has invalid signature [ ð], must be SSDT, PSDT or OEMx [20070126] [ 51.192790] ACPI Error (psparse-0551): Method parse/execution failed [\_PR_.CPU2._PDC] (Node df848240), AE_BAD_SIGNATURE I have attached dmesg. ** Attachment added: "Dmesg output" http://launchpadlibrarian.net/10811834/dmesg.txt -- ACPI Warning: Incorrect checksum in table https://bugs.launchpad.net/bugs/133146 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
