Looks like 8bd108d14604d9c95 added ACPI_PREEMPTION_POINT() in acpi_ps_complete_op(). But now on boot in linux-next I get streams of BUG() like below (always seems to be with swapper) This is a linux-next kernel from Aug 21 on vmware server 2.0. -Eric [ 4.241159] BUG: scheduling while atomic: swapper/0/0x10000002 [ 4.242308] no locks held by swapper/0.
