Hi! Dear maintainer,
I have a problem getting hibernate from this machine. After issuing hibernate command via kernel 'echo disk > /sys/power/state' or systemd 'systemctl hibernate', the screen is black but still powered on. After like 20secs, fan speed ramp up to max. If I disconnect the power (mind that my laptop battery is detected bad) it's instantly turned off (like if I disconnect power on bios menu) -- my guesses is the blank state is likely stuck on the bios mode/side(?)
I've tried to located the problem by blocking amdgpu modules from booting and I found out that amdgpu likely the problem. I tried upgrade kernel on ubuntu to 5.8 but no amdgpu loaded but using LLVMpipe mode, the hibernate can happen normally
There is no/I don't know where the - serial port on this device as this is a laptop and I have limited knowledge/resources to find that out.
I guess that's useless to attach dmesg, as system is not recording any logs occur after hibernate issued.
Another thing I get is from the Magic number (PM_TRACE), they said some error on random 'memory48' or sometimes 'memoryXXX'. I think this may be just false positive [ 0.984201] kernel: PM: Magic number: 11:0:0 [ 0.984292] kernel: memory memory48: hash matches
Here's some device details.
Thank you.
