Thanks for the fast response!
Sorry, I was only using Pastebin because of the instructions provided on the initial post:
Nonetheless, I have added textfiles with the contents of the previous post. Furthermore, please find the requested diagnostics attached to this post as well (plugin currently showing Kernel module & Version).
I have only set up everything using 6.10rc2 so I can't compare to other older versions. However, if nothing else helps I am willing to downgrade and try 6.9.2 in order to see if the problem persists. Can't think of any BIOS updates or changes recently, so that shouldn't be the cause. Or can you think of a setting that might send the card into some kind of sleep mode?
What I have done are some changes to my Syslinux configuration (see screenshot).
No new hardware either.
