The ACPI error messages indicate a bios problem. The _TPC methods in the SSDT refer to a number of variables named TST0, TST1, TST2, and TST3 that aren't defined in any of the ACPI tables. The ACPI errors are simply stating that these variables are referenced but not defined. We can't really do anything about the errors.
Whether or not these are related to your lockups is unclear. The missing variables are an issue that Linux can handle, so those aren't directly responsible. However, the _TPC method is associated with power state throttling, so it's plausible that the failed method execution could cause the processors to be operating at a higher power state than it ought to be and that this leads to your lock-up. There's no clear evidence that this is actually the case, however. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
