ACPI AML supports "serialized" methods which are protected by an implicit mutex. The mutex is re-entrant for that AML thread to allow recursion. However, Linux implements notify() by creating a new AML thread. So for systems where notify() re-enters a serialized method, deadlock results. The fix is to use the Linux thread_id as the key to allowing re-entrancy, not the AML thread pointer. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com> |
