Debug build of ACPI 3.15 crashes with debug kernel

Description (last modified by Steven Levine)

When loading the SMP debug kernel with the retail ACPI 3.15 I get a trap (sorry for the layout)

(Sorry for the bad outlining).

It does not always happen but in about 60% of the boots (seems most happens after a cold boot). Also from the quick research Steve has done it seems to be in SCREEN01.SYS.

But the trap did not occur before on my laptop. So need more research to come with data its ACPI 3.15. Also with retail kernel loaded this problem also does not occur.

Summary: Retail build of ACPI 3.15 crashes with debug kernelDebug build of ACPI 3.15 crashes with debug kernel

This trap is the SpinlocksOwned? trap that has been observed previously (see ticket #320). It is triggered by adding the /O1 switch to the PSD=ACPI.PSD command line.

The debug kernel traps because it checks SpinLocks? owned in intIRQRouter. This check does not exist in the retail kernel, so there is no trap.

If possible, the acpi should be updated to release the spinlocks before generating debug output or bypass the output if spinlocks have been acquired and running under the debug kernel.
