Wow! This did away with the once-a-minute error messages from Notify()s on processor objects on my laptop. However, I am now getting frequent panics from from a GIANT_REQUIRED assertion in kmem_malloc(). kmem_malloc() gets called via malloc() from AcpiOsAllocate(), without Giant locked. The call to AcpiOsAllocate() happens deep in a AML object evaluation in from acpi_tz_thread(). I tried naively to modify AcpiOsAllocate to grab Giant before malloc() and release it afterward, but this appears to be a very bad idea: There is a mtx_assert(&Giant, MA_NOTOWNED) in ithread_loop() in kern/kern_intr.c which blows up during boot.
