It was connected to AC power with a full battery, if that is significant. Kernel is 2.4.0-prerelease. The machine is a IBM Thinkpad i1200 series (to be more specific model 1161-267), Coppermine Celeron CPU 550MHz, 64MB RAM, BIOS updated to 1.0R. This machine works fine under APM except that it sucks as much power on suspend than when running (LCD and HD shut off, that's all). With ACPI I have the contrary problem that it goes into CPU powersave even when it should be running normally. The userspace bogomips program normally reports 546bm but only 64bm when running ACPI (and it is slow; kernel cpuinfo reports 1040bm in both cases, it is reduced in speed only after kernel did its own measurement). This could be related to the kacipd failure however. -- Andreas E.
