Re: [Intel-gfx] intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Dear Lakshminarayana, dear Chris, dear Jani, thanks for opening this bug, but it seems nothing to happen with that. Can I do anything to trigger this and bring that back to focus. It is an really annoying bug and this flickering screen drives me crazy and with "intel_idle.max_cstate=4" runtime is dramatically reduced. From what I read maybe you Chris have biggest knowledge. Can you give me some feedback? Shall I give up hope?
