Ah ok, I didn't know that. Thanks for the info - I'll try the option and see how it goes ;-)
Unrealted to the acceleration I discovered another error message in my dmesg: [drm:ci_dpm_set_power_state] *ERROR* ci_upload_dpm_level_enable_mask failed Should I report that in a new bug ? (I should really stop hijacking this bug, sorry)
Yes, open a new bug for the dpm stuff. In the new bug please note whether this is new after applying attachment 93015 or if this was always there.
