I have this LOR every time I boot:

lock order reversal

 2nd 0xc0a18000 ACPI root bus (ACPI root bus) @ /usr/src/sys/modules/acpi/acpi/../../../dev/acpica/acpi.c:913

I know this has been reported and is registered as LOR 026. It has got a
status patchet. Doesn't it meen, that I should not get this LOR when it
is patched?

Could it have be somehow connected to Bugreport #70832 ?

(Sorry, if this is a spam :-( )
