I have it since ~2.4.14, and until 2.6.8.1 the 'halt' command shut down the machine correctly. Starting with 2.6.8.1-bk1 it reboots. :( I realize that -bk1 has a big ACPI update, which may be the problem IMHO. I have tried to look into existing bugreports, but could not find any similar to this on the Kernel Bugzilla nor in the ACPI Bugzilla. All I could found some note that Local APIC can cause problems, but even if I disable that, the problem remains. Asked LKML without any reply; hope here I can get some help, so if you need more information about it, please let me know. Some maybe relevant bits from the machine: 0000:00:00.0 Host bridge: VIA Technologies, Inc.
