--- Comment #3 from Lakshmi <lakshminarayana.vudum at intel.com> ---

@Imre, Is it worth trying to verify this issue with drmtip?

(In reply to Val Kulkov from comment #2)
> The regression was present in the mainline kernel as of 2019-10-24.
Val, can you attach the dmesg from boot with kernel parameters drm.debug=0x1e
log_buf_len=4M ?
