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.

Above comment is valid for bug 111883 as well? @Tomi, Need your help in fixing this bug.
Added trace_clock=global WA for fi-cml-s. Will show up in run CI_DRM_6995 and later

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.
