Mostly suspending to RAM works, but occasionally it ends with screen off but power lamp fully lit, and it is not responding to anything - not even REISUB - except holding power button > 4s to cut power. Power on leads to normal boot, user work not saved. This is on my Thinkpad T510, which also have problems powering off when entering hibernation, see https://bugs.mageia.org/show_bug.cgi?id=33107#c44 Looking in journal i see no difference between successful and failed suspend except it just stop logging. And stopping logging is of course normal but i dont know at what point it is normal to stop. This is with kernel 6.6.28-desktop-1.mga9 I will try the linus kernel to see if it seem to be better or worse. $ inxi -SMCG System: Host: localhost Kernel: 6.6.28-desktop-1.mga9 arch: x86_64 bits: 64 Desktop: KDE Plasma v: 5.27.10 Distro: Mageia 9 Machine: Type: Laptop System: LENOVO product: 4349A13 v: ThinkPad T510 serial: <superuser required> Mobo: LENOVO model: 4349A13 serial: <superuser required> BIOS: LENOVO v: 6MET92WW (1.52 ) date: 09/26/2012 CPU: Info: dual core model: Intel Core i5 M 540 bits: 64 type: MT MCP cache: L2: 512 KiB Speed (MHz): avg: 1273 min/max: 1199/2534 cores: 1: 1314 2: 1323 3: 1260 4: 1197 Graphics: Device-1: NVIDIA GT218M [NVS 3100M] driver: nouveau v: kernel Device-2: Lenovo Integrated Webcam [R5U877] type: USB driver: uvcvideo Display: x11 server: X.org v: 1.21.1.8 with: Xwayland v: 22.1.9 driver: X: loaded: modesetting,v4l dri: nouveau gpu: nouveau resolution: 1920x1080~60Hz API: OpenGL v: 3.3 Mesa 24.0.5 renderer: NVA8
Created attachment 14549 [details] journal of suspend-resume with comments This is a journal log of *successful* suspend-resume. When failed it just stops, and i have commented where. The idea is to see what steps normally is performed, and a problem i sto see what goes wrong when saving of the log to journal seem not to be performed until resume, which of course is not performed as I have to cut power...

One idea: If it is trying to do something with the GPU, it may be this that strike: Bug 33209 - Occasional screen freeze due to nouveau page fault But I would guess it is more likely to have similar problem with power state manipulation i both end of suspend, and end of hibernation: https://bugs.mageia.org/show_bug.cgi?id=33107#c44
