OK, with -rc7 and the i915 fixes, there seems to be a marked improvement. I can no longer crash the crtc by using lots of xrandr switches, which was the principal problem. I've so far only got one of these in the logs [14858.635035] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun And the only residual problem seems to be that the monitor goes blank periodically, but this can be fixed by switching resolution a couple of times. I haven't seen any of the link training errors so far and I've run through my usual battery of be nasty to the external monitor tests.
