jkim 2009-09-02 16:02:48 UTC FreeBSD src repository Modified files: sys/amd64/amd64 pmap.c sys/i386/i386 pmap.c Log: SVN rev 196769 on 2009-09-02 16:02:48Z by jkim - Work around ACPI mode transition problem for recent NVIDIA 9400M chipset based Intel Macs. Since r189055, these platforms started freezing when ACPI is being initialized for unknown reason. For these platforms, we just use the old PAT layout. Note this change is not enough to boot fully on these platforms because of other problems but it makes debugging possible. Note MacBook5,2 may be affected as well but it was not added here because of lack of hardware to test. - Initialize PAT MSR fully instead of reading and modifying it for safety.
