After updating again I’m at kernel version 6.14.4-300.fc42.x86_64 and it’s not immediately happening.
I’ll reply again if the issues manifest once more. It hasn’t been super easy to intentionally reproduce, but typically happens within a few days of using the laptop regularly.
For other details:
Model: Framework Laptop 13 AMD Ryzen 7040 Series
Memory: 32 GiB
Processor: AMD Ryzen™ 5 7640U w/ Radeon™ 760M Graphics × 12
Firmware Version: 03.07
Edit: I should note that I’ve had a number of other freezing and crashing issues, in case they are linked in some way, some of which I’ve noted in replies to [RESPONDED] Laptop crashes and reboot sometimes after resuming from suspend, and some that seem slighly different but might have the same cause (like screen freezing while cursor keeps moving, or screen anc cursor freezing while audio keeps playing, or some combination of those before a black screen and then the login screen).
