 - for the odroid x the file extlinux/extlinux.conf in the first partition needs to be edited - see the comments in the file
 - a fixed ether mac address is set in the same file and can be changed if multiple such devices are running in the same network or omitted to get a new random ethernet mac address on each boot
 - the odroid u3 (and the others most probably too) seems to be very sensitive to stable power supply, so if you see strange crashes on boot, check if the power supply is good enough
-- suspend/wake/hibernate seems to be working at least on the odroid u3 (the others were not tested yet), resume is done via the physical button
+- s2idle and deep suspend seem to be working at least on the odroid u3 (the others were not tested yet), resume is done via the physical button (tested with v5.19.1 on debian bullseye, but it was already working before as well - hibernation not tested this time, but could be that it was tested to be working back then, so it might even be working too)
 - there is a thread on the odroid forums about running mainline on the odroid u3 at https://forum.odroid.com/viewtopic.php?f=55&t=3691&sid=1a9bcfd371f8be232c2620b64bad2150&start=450
