--- Comment #23 from Joey Lee <jlee@xxxxxxxx> ---
(In reply to Dominique Leuenberger from comment #21)
possible related upstream bug:
https://bugzilla.kernel.org/show_bug.cgi?id=192111

In bko#192111, Ivan bisected out that the bad patch is 8b355e3bc.

The result is possible because acpi/osl.c uses synchronize_rcu_expedited to
speed up grace period in acpi_os_map_cleanup() since v3.19:

74b51ee152b ACPI / osl: speedup grace period in acpi_os_map_cleanup


The detail of 8b355e3bc needs RCU expert's comment.
