Pinephone Mobian

[Formal_Muffin_5664]

Pinephone freezes after a couple minutes with kernel 5.9 5.10 and 5.11 after last update
Geary doesnt start and pinephone doesnt recover anymore after sudo reboot or deep sleep
Only hard reset will start again

The current  up-to-date Mobian kernel is 5.10 - it is unclear what you have done to your installation to be toggling between 5.9 and 5.11? While a 5.11 kernel is manually installable it is clearly experimental at this stage as per another thread.
