--- Comment #10 from Matt Roper <matthew.d.roper at intel.com> ---
All of the warnings here seem to arise following suspend-resume, which is a
known system clock issue on some platforms.  The warning message itself
suggests a rememdy:

    If you just came from a suspend/resume,
    please switch to the trace global clock:
      echo global > /sys/kernel/debug/tracing/trace_clock
    or add trace_clock=global to the kernel command line

This isn't related to the graphics driver and is a platform-specific quirk, so
we should probably take the warning's advice and update the boot command line
for fi-cml-s to include the "trace_clock=global" to avoid hitting this.
