These are only called during X server startup.
> va/drm/va_drm_utils.c: name = drmGetDeviceNameFromFd(fd);
This should only be called when a video player using VA-API runs standalone,
not via X (or Wayland), and even then only once.
Try running
sudo perf record -e rpm:rpm_resume --call-graph=dwarf
in a terminal, then do whatever is needed to reproduce the problem, then
interrupt the perf command with Ctrl-C and attach the output of
sudo perf report --header
