Some things to test for users in alpha channel since kernel has MTE enabled (from GrapheneOS account in Alpha/Beta testing channel on Matrix) :
- Bluetooth
- NFC
- DisplayPort alternate mode,
- Wi-Fi Direct
- any other niche hardware functionality
- BLE Audio
- USB peripherals (USB-C audio, mouse, keyboard, joystick)
- Controller like xbox controller etc
- Drives with exFAT and Fat32
- Stress test on GPU, disk etc
- Weird games, emulators
Edit : If you're on 8th or 9th gen Pixels and testing this release, please enable system crash notifications in Settings > Security & privacy > More security & privacy > Notify about system process crashes so you get kernel crash notifications after a kernel panic reboot in case hardware memory tagging finds any kernel bugs.
