 I suspect this this is probably a red herring, like this one, where
 there was an ACPI warning message that had nothing to do with the
 silent hanging thread:
 
 https://gnats.netbsd.org/56404
 
 We really need to know what's hanging here, e.g. by entering ddb and
 getting a stack trace.
 
 Can this still be reproduced?
