I've experienced literally dozens of this since upgrading from 5.9.6, which worked flawlessly.
The RAM was tested a number of times with both MemTest86+ 5.01 and MemTest86 V8.4, and no errors
have been found ever. It may be also related to some security shit switched on in the kernel by default,
but then I need a way to switch it off -- what the f do I need a "secured" system for, if I can't use it?
