OK. We still have the time :-) Enable CONFIG_SND_DEBUG and use it for months. If it occurs again, we at least have more error messages. Otherwise it at least demonstrates itself to be some less disturbing bug :-) > I looked at the latest dmesg after yet another reboot and see only a > single "[drm:intel_hdmi_mode_set], Enabling HDMI audio on pipe A" event, > and no misreads.

For now let's treat it as some hardware mysteriousness...
