Hi, This I think has come out before (although I'm unable to find the emails); but now it is happening to me as well, and I have new info. I have SuSE 8.2, recently updated from 8.1. The system will not halt (only reboot): at the last moment it freezes and enven the keyboard leds stop responding. If I switch to console 10 before the lock, I see this message (copied by hand): ACPI-1121: *** Error: Method execution failed [\SALD] (node efe3dc0), AE_AML_UNINITIALIZED_LOCAL ACPI-1121: *** Error: Method execution failed [\PTS] (node efed5c0), AE_AML_UNINITIALIZED_LOCAL My kernel is 2.4.20 from SuSE. It failed with the one from the DVD, the patched one (YOU --> k_deflt-2.4.20-96), and my compiled version of same. Needless to say, it worked perfectly with suse 8.1, with both acpi and apic enabled. Ideas?
