Re: kernel 5.15.1: AMD RX 6700 XT - Fails to resume after screen blank

Hi Greg,

I'll can try reverting that patch, and check.

This hardware has been stable with all kernels from around 5.11 up to and including 5.15.

Cheers,

Mark

Hi all,

I run the mainline Linux kernel on Ubuntu 20.04, built from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.1/

There appears to be a regression in 5.15.1 which causes the GPU to fail to resume after power saving.

Could it be this change??:

If you revert it, does it solve the problem for you?

If not, what kernel version did work for you with this hardware?

thanks,
