On an Odroid H4 (Intel N97 Alder Lake x86 SBC) attempting resume from S3 sleep now results in a locked up state where system powers on but does not progress to restoration of OS & Kodi state.
It's a hard lock-up - doesn't respond to the reset button and requires a 4-second press on PWR to force hard power off. System does a normal cold boot at next power-on.
Has something fundamental changed in LE13 with the resume/sleep management ? (Maybe kernel version or something in the Linux scaffolding of LE's x86 build ?)
For further information, state & meaning of the 5 onboard diagnostic LEDs:
- Red (PWR) – Solid light when DC power is supplied
– Blue (left, SLEEP) – turns off only when the system enters into suspend mode
– Blue (right, PMIC) – turns on only when the major power rails are working
– Amber (SATA) – Flashes when SATA data transfers
– Green (NVMe) – Flashes when NVMe data transfersIn normal powered-down state with PSU still connected:
\ Red \ - - - - \ - - - - \ - - - - \ - - - - \
In regular powered on running state (Amber & Green flash as disk I/O happens) :
\ Red \ Blue-L \ Blue-R \ - - - - \ - - - - \
After a failed resume the system LEDs show:
\ Red \ Blue-L \ - - - - \ Amber \ - - - - \
The presence of the solid Amber LED (SATA) seems slightly anomalous - there are no SATA devices present, the only disk in the system is an M.2 NVME
In normal operation and with prior LE12 builds the Green NVME was the only I/O LED that flashes at any point.
Grasping at straws ... Perhaps something is making a faulty assumption that a SATA device should be present, and is hanging the resume process as it waits for a response that will never come ?
I am somewhat stuck at this point as I don't have a further way to diagnose the resume process - logging stops in what looks like a normal manner after S3 sleep is triggered and proceeds to shutdown state. Given that I have to hard power-off and cold boot after this point there isn't any logging available for the S3 resume sequence, just the kodi.old.log to the point of sleep shutdown.
Any pointers would be appreciated.
