Hi,
In the past few days since I've upgraded to 25 I've been getting the following errors in the logs:
[ 208.023766] perf: interrupt took too long (2514 > 2500), lowering kernel.perf_event_max_sample_rate to 79000
[ 765.749837] perf: interrupt took too long (3157 > 3142), lowering kernel.perf_event_max_sample_rate to 63000
[ 1062.805232] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
[ 1475.373597] perf: interrupt took too long (3949 > 3946), lowering kernel.perf_event_max_sample_rate to 50000
Don't know if it's something to be concerned about or not?
