after installing Kubuntu 26.04 (kernel 7.0.0-27-generic) on my Lenovo IdeaPad Slim 3 15ARP10 (83MM, Ryzen 7 7735HS), I found that sometimes when the laptop suspends after idle, it won't resume. Pressing any key has no effect, and pressing the power button once doesn't help either. The only way out is holding the power button to force a restart.
I tried adding amd_pmc.enable_stb=1 to GRUB but it didn't solve the problem. The issue is intermittent and I haven't found any pattern yet.
Any help is appreciated.
