Hey there,
just trying, maybe someone has an idea for me:
I’ve got a Ryzen™ 9 7940HS with the AMD Radeon™ RX 7700S expansion board. Factory build. Currently I have EndeavourOS installed.
Now for the fun part: While everything else is running just fine, whenever the Notebook goes to Suspend or Hibernate, after returning it puts the right fan (it seems) spins up to full RPM, just leaving it there until a full power cycle (shut off). Simple reboot does not help.
The left fan seems somewhat unaffected, adding a lot of CPU load makes that spinning up, too - but getting the load down also makes it roll back again.
I think I tried all of my tricks, maybe someone could give me a hint in the right direction for something to check …
Since the Notebook is like 3 days old, there never was an old kernel to begin with
As far as I can establish, it might go into the direction of the ACPI thermal zone bug, that should have been fixed somewhere around BIOS / Firmware 3.03 (see: this post and/or around Kernel 6.9), which makes me wonder:
If I have the Expansion Bay Shell in, I’ve got 4 ACPI thermal zones (0-4), all of them showing proper temperatures (sensors). Suspend and Hibernate both work fine.
If I add the AMD Radeon™ RX 7700S expansion board, there are 4 zones added (4-7) for a total of 8. But: I get the error
The GPU has Firmware 113-BRT125778.001 as per gnome-firmware, with no newer firmware available as to fwupdate:
$ fwupdmgr update

• Fingerprint Sensor

The moment the card comes back in, I get a report from sensors like this:
