The first patch is not enough.
Yes, it fixes the system hang when I launch the game "Find the Orange Narwhal".
But it does not fix the issue completely.
Some RenPy games still can lead the system to hang.
For example "Innocence Or Money Season 1"
https://store.steampowered.com/app/1958390/Innocence_Or_Money_Season_1__Episodes_1_to_3/
on the language selection screen.

Unfortunately the kernel is not builded with both patches.
I have got compilation error after applying second patch:
