Author: mav Date: Sun Sep 9 20:00:00 2012 New Revision: 240286 URL: http://svn.freebsd.org/changeset/base/240286 Log: At least from A70M FCH chipsets AMD started to use their real vendor ID (1022) in HPET. But according to report they still haven't fixed problem with level-triggered interrupts. Make workaround used for earlier chipsets apply to this new ID also.
