  LS,

  Recently I bought a Radeon RX 6600 XT card from Gigabyte. But I noticed
quite
quickly that my system has issues. 95% of the time I try to wake the system
-
only the screen is switched off after sometime, no system suspend - the
system
input and display freezes.
  I noticed that the drive LED is still working, so assume that the rest of
the
system is still working.

  Thinking that the PSU might not up-to it's task with this new card, I
upgraded
that too. It seemed to go better, but still have these freezes from time to
time.
  Below is a snippet from the log file around the time the system freezes.
The
GPU seems to have issues, from which the software does not seem to recover:

Frans:

I mean they are a hardware problem, like the PCIe specs, because Your
motherboard is PCI-Express 2.0, and the video card is PCI-Express 4.0.

I have a motherboard Asrock 980DE3/U3S3 (PCI-Express 2.0) with a
FX-8320E CPU and a Radeon RX-580 GPU without issues in Tumbleweed.

Regards,
               Juan

  Oh, I thought it was an PCIe-3.0 version of the bus, but your right: finally
checked the manual ;)
    For many years I tried to avoid to upgrade the CPU with ditto MB since the
system is still running good and is fast enough for what I am doing - Office,
Video/Audio processing, Development. To keep the system running, I now need to
switch to the system console whenever I pause using the system. This is because
that console does not get switched off during the display sleep. This means a
constant power usage for no practical use. This is currently my only workaround
that seems to work.
    After my switch to an 4K monitor, I had to retire my NVIDIA GF9600 GTX card.
But due to the lack/availability of modern passive cooled AMD graphics cards, I
needed this card with it's semi-active/passive cooling. I don´t play games on
the computer - maybe when I am getting senile I might ;)
    So, I for now stick to switching to the system console from time to time and
hope there is a fix for it in the future.

In thery, PCIe 4.0 should work in a PCIe 2.0 slot. I still think it might be
worth trying a 5.16 kernel as I suggested in the bug report.

There are others with similar problems:

As soon as Tumbleweed offers this, I can try this. I might take a week or so after launch of 5.16, before OpenSuse will provide it.
