--- Comment #36 from Rev (rev at pop.ms) ---
I still get around 700 error logs per day on my 24/7 PC. 

amdgpu 0000:06:00.0: [drm] *ERROR* No EDID read.

I am using the standard-kernel of ubuntu 24.04 LTS now (6.8.0-36-generic), with
the standard mesa (24.0.9) drivers that come with the OS.

Display standby's and wake-up's work as intended tho in ubuntu 24.04. Putting
the whole system on standby and waking it up works since the change from ubuntu
22.04 to 24.04. 

So for me it is not an issue about a function. It is an issue that is most
prominent in the logs of ubuntu. If I did not review the logs I would never had
known about wake-up issues in 24.04, that was different in 22.04. Putting the
PC in standby in 22.04 meant never waking up the display again and the need of
a cold boot.

But an average of 700 error messages per day means there is something not
working right, imo. And since that is a very, very old issue since a far older
kernel version, and a lot of AMD gpu users out there, I would like to help. But
I am not a tech expert, just a user who can read stuff and do stuff a bit
better that an average user. So please, if you want some more help from users
with that issue, please explain how we can help for a solution and I would
guess people would contribute their information to help solving this issue.

Sorry for the long winded comment.
