After booting, the machine freezes (hard-lock) when tryin= g 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 lin= es 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_s= witcheroo is built into the kernel. --=20 Best regards, J=F6rg-Volker.
