Maybe that could help narrow down where it hangs. The problem is the driver is not really involved except for the initial programming of the states. The GPU does the reclocking internally once it's enabled. Best bet would be to adjust the values programmed into the state that's loaded into the SMC to see if you can narrow down what aspects are problematic. -- You are receiving this mail because: You are the assignee for the bug. --1383862459.8b67c2.11027 Date: Thu, 7 Nov 2013 22:14:19 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8"

The problem is the driver is not really involved except for the initial
programming of the states.  The GPU does the reclocking internally once it's
enabled.  Best bet would be to adjust the values programmed into the state
that's loaded into the SMC to see if you can narrow down what aspects are
problematic.
