[StarBook Mk IV - Intel] S3 Exit not working on Ubuntu 22.04

[netmonk]

received my starbook yesterday, updated firwmare to 8.22, running ubuntu 22.04 preinstalled.

Suspend/Resume is not working at all, each time i close the lid and reopen it few time later i have to power down and power up again while laptop rebooting from 0.

Is there any solutions for this issue ?

Interesting - what happens when you open the lid? Blank screen?

Can you let me know your kernel version (uname -r)?

[netmonk]

plonky@nano:~$ uname -r 5.15.0-58-generic

at first the backlight of the keyboard switch on, but screen stays blank, nothing happens. Now, i dont see the backlight of keyboard switching on anymore.

Any news ?

Just testing 8.23 now, S3 bugs take a while to test but it's public if you want to try it out

Good evening, I just installed 8.23 firmware, it doesnt seems to fix the issue, still need to force shutdown after suspend to have the screen powering on and system booting for zero again. The Resume step is not working (may be cause the suspend step is in failure i dont know )

Also 'sudo reboot' doesnt reboot.

Hmm, are you able to switch to the AMI firmware and see if you can reproduce it there? I haven't been able to replicate it on 8.23

[netmonk]

where can i find th AMI firmware ?

Can no longer replicate with e93a096e9da512371e8c5eec8ff03884487aabfa, will leave testing over the weekend and then push

well the problem is not replicable after endeavouros installation. I have another laptop with ubuntu and suffer same issue. So it' more tied to ubuntu and kernel than hardware firmware from my perspective.

Also, can i use upstream flashrom to flash firmware or do i need to use starlabs fork ?
