Thanks for clarifying. Does this behavior happen in multiple expansion slots? Also (forgive me if I already asked this, busy Monday), have we tested to see if this works on another distro? Worth running a Live Fedora ISO for example.
If additional distros have similar experiences, it may be a bad card. If they do not however, then it may be worth testing another distro further as it could be related to the packages installed, kernel, etc.
My troubleshooting flow for stuff like this is as follows:
- Tested all slots, same result.
- Tested a live USB of another unrelated distro, if it works, note the kernel and the package versions if possible.
Officially supported are Ubuntu and Fedora, GNOME desktop, as that is what we test with. I’d start there.
Even though this feels like a power issue with how Arch is interacting with the card, I’d start with the suggestions above as it will allow us to determine if this is software/OS or hardware.
