Subject: acpi schedule() calls rely on taskswitch?
Date: Mon, 5 Sep 2011 17:46:21 +0200 [thread overview]
Message-ID: <20110905174621.1a4d2a31@aplus> (raw)
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.
Thanks,
Markus
