However, it looks like this fails, as the last kernel message is > > *ERROR*: switching to FCLK failed There are two places in the code in intel_display.c where that error is reported. Both look like this: if (wait_for_atomic_us(I915_READ(LCPLL_CTL) & LCPLL_CD_SOURCE_FCLK_DONE, 1)) DRM_ERROR("Switching to FCLK failed\n"); The last argument is effectively the number of times DELAY(1) is called. Could you try changing the 1 in those calls to 10?
