Hello Dave,

on my HP Pavilion dv7 there is still with 3.5-rc3 a severe problem with the
dynpm option. After booting, the machine freezes (hard-lock) when trying to
switch to dynamic power mangement on the integrated GPU via

echo -n dynpm > /sys/class/drm/card0/device/power_method

at least two trace calls are done. On the console only the last two lines of one
call trace and the last one are visible (machine is frozen). Debugfs is not
mounted. On demand I can deliver further information.
The system has two AMD-GPU (Mobility Radeon HD 4200, HD 5400) and vga_switcheroo
is built into the kernel.

Best regards,
