Author: royger Date: Thu Aug 7 17:00:50 2014 New Revision: 269675 URL: http://svnweb.freebsd.org/changeset/base/269675 Log: atpic: make sure atpic_init is called after IO APIC initialization After r269510 the IO APIC and ATPIC initialization is done at the same order, which means atpic_init can be called before the IO APIC has been initalized. In that case the ATPIC will take over the interrupt sources, preventing the IO APIC from registering them.
