Thank you for paying attention to this. I am using Debian stock kernel # uname -a Linux raspi4-bullseye 5.9.0-1-arm64 #1 SMP Debian 5.9.1-1 (2020-10-17) aarch64 GNU/Linux in Debian testing on Raspberry Pi 4B, but # find /proc -name \*align\* -print shows nothing... I don't have /proc/cpu/alignment... Ryutaroh
