However, during suspend/resume it runs with irqs disabled to evaluate _GTS/_BFS, as well as by irqrouter_resume() which evaluates _CRS, _PRS, _SRS. http://bugzilla.kernel.org/show_bug.cgi?id=12252 Signed-off-by: Wu Fengguang Signed-off-by: Len Brown --- diff --git a/include/acpi/platform/aclinux.h b/include/acpi/platform/aclinux.h index 029c8c06c15..0515e754449 100644 --- a/include/acpi/platform/aclinux.h +++ b/include/acpi/platform/aclinux.h @@ -141,6 +141,10 @@ static inline void *acpi_os_acquire_object(acpi_cache_t * cache) /* * We need to show where it is safe to preempt execution of ACPICA */ -#define ACPI_PREEMPTION_POINT() cond_resched() +#define ACPI_PREEMPTION_POINT() \ + do { \ + if (!irqs_disabled()) \ + cond_resched(); \ + } while (0) #endif /* __ACLINUX_H__ */
