Between the vmallocinfo and printk code, it looks like you need to set /proc/sys/kptr_restrict to 1 and be root (or have CAP_SYSLOG privilege) to get non-hashed addresses here. Because having only one way to confuse debugging would be far too easy, I guess :/ Robin. > # uname -r > 5.13.0-00009-g8beacec9a060 > # cat /proc/cmdline > console=ttymxc1,115200 no_hash_pointers > #
