 This is definitely specific to ThinkPads. It can be reproduced with other
 60-61 series such as X61. But I think this is present in Linux as well (and
 maybe even Windows).

 BTW, the only time I see this is after a crash!  I have never seen it
 otherwise.

 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?
