Hi, I am currently testing an alternative CPU-scheduler and have problems when ACPI is activated. If the scheduler does not change the currently running task after a call of schedule(), the kernel hangs with ACPI activated. The kernel has no problems with acpi=off. Is there any ACPI code that relies on a taskswitch when calling schedule? I saw this behaviour with linux-2.6.38.6 and an AMD Athlon II M320.
