Re: [LTP] arm64: Unable to handle kernel execute from non-executable memory at virtual address ffff8000834c13a0

[David]

Hello,

On sdm845 cheza board, with 6.5.4 (before running 6.4.x), I saw this 
issue too. Happened only once, but I can try stress-test it how often it 
pops up.
Whole log is here [1]. Used kernel is referenced from full log, kernel 
extra patches [2].
