System is still accessible via SSH after resume from standby. Happens when X is running (gdm/gnome with 3d acceleration) and also when X is stopped. Also the computer never really goes into standby. The cpu fan is running all the time and the power button is fully lighted up. Nevertheless, I need to press CTRL to "wake" it, so I can access it via SSH. I'll attach the dmesg output of several attempts. This is the hardware: https://store.hp.com/GermanyStore/Merch/Product.aspx?id=9YN58EA&opt=ABD&sel=NTB Tested EFI and BIOS bootmode. Please let me know if I can help tracking this down. I'm a software developer (sadly not a kernel developer), so you can ask dirty technical questions ;-) Workaround: Enable hibernation (suspend to disk) and use instead of suspend to ram (standby). What didn't help: Kernel parameters: no_console_suspend nomodeset amdgpu.gpu_recovery=1 init_on_free=0 idle=nowait amd_iommu=flush echo mem > /sys/power/state systemctl start suspend.target echo 0 > /sys/power/pm_async Upgrading kernel from 5.4 to: 5.6.0-1010-oem Using the kernel parameters no_console_suspend nomodeset amdgpu.gpu_recovery=1 init_on_free=0 idle=nowait amd_iommu=flush and doing echo mem > /sys/power/state before suspend made the system acutally not crash. Nevertheless, the cpu fan and the power button stay full on/lighted. So the system doesn't really go to standby either. I'll try to find the minimal combination of kernel parameters. nomodeset seems to be essential, but not sufficient. Without nomodeset the system wakes again for a few seconds, but freezes a moment later (ssh still accessible).
