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