I recently changed Wi-Fi cards and started experiencing crashes. Switching network managers, init systems, and browsers did not work, but switching from linux to linux-lts did.
After shutting down from a crash, dinit mentioned this.
eth0: NIC Link is down
When I tried shutting down after switching to OpenRC, there was a mention of [drm] GPU and an error about unmounting file systems.
If I waited too long, all keyboard input was locked, and I had to remove the laptop's battery. Sometimes, the Caps Lock key flashed, indicating kernel panic. Some examples that caused the crashes were
- playing a video, closing the laptop for it to suspend, and reopening the laptop
- pressing next on a Google form
- joining a Zoom meeting
- doing actions that use plenty of bandwidth, such as loading many videos
