Comment 10 Matt Roper 2019-10-02 20:11:56 UTC
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.

@Matt, How about Bug 111883? Above comment is valid for bug 111883 as well?

@Tomi, Need your help in fixing this bug.
Comment 12 Tomi Sarvela 2019-10-03 07:07:14 UTC
Added trace_clock=global WA for fi-cml-s. Will show up in run CI_DRM_6995 and later

Yes, thanks for pointing that one out.  It looks like the same platform clock problem is present on that snb platform.  I can't verify for sure that that machine doesn't already have the trace_clock option on the kernel command line since the boot.txt link over there is broken, but assuming it doesn't we should also add it to that machine.
