Xavier AGS reboots on dmidecode


this is probably related to https://devtalk.nvidia.com/default/topic/1047866/general/fatal-fault-locks-up-the-xavier-soc/ . I experience instant shutdown (and reboot) after issuing sudo dmidecode. Without sudo dmidecode can’t work but at least gives an error message about that:

dmidecode 3.1

Scanning /dev/mem for entry point.
/dev/mem: Permission denied

Here follows what happens:
nvidia@100days-xavier:~$ sudo dmidecode
[sudo] password for nvidia:

This tools should not support on ARM system due to there’s no BIOS on ARM’s arch.
