Failed to properly resume from S3 (suspend-to-ram) on kernel version 5.13.0-16 (installed while updating to impish), amdgpu driver.

[KOLANICH]

On 5.11.0 everything is OK.
The GPU is AMD Carrizo APU.

UPD: I have checked several kernels for presence of this bug

Experiencing the same problem after upgrade to Impish. I have determined that the desktop does actually start after a resume from suspend, but the screen remains blank, with the backlight on. (To determine this, I used a keyboard shortcut to launch a terminal window and typed a reboot command successfully.)

Everything in the kernel log seemed normal for the interval around the suspend/restore (although there's so much stuff there, it's hard to be sure.)

The screen does come on OK after a full reboot.

As with the OP, suspend/restore is OK if I back off to using the 5.11 kernel. Also as for the OP, my system is using the amdgpu driver.

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem here :
AMD Radeon R7 Graphics (CARRIZO, DRM 3.41.0, 5.13.0-21-generic, LLVM 12.0.1)

[Paweł Szmergała (pawel-szmergala)]

I'm experiencing the same issue with kernels:
5.13.0-28-generic,
5.13.0-30-generic,
5.13.0-35-generic.

GPU AMD ATI 03:00.0 Lucienne

However, it doesn't occur with kernel 5.13.0-27-generic.
