We are running the Zabbix agent 4.2 with root on Ubuntu 16.04. Only on our newer ProLiant Gen10 servers the agent is unable to retrieve any information from system.hw.chassis[].
# zabbix_agentd -t system.hw.chassis[serial] system.hw.chassis[serial] [m|ZBX_NOTSUPPORTED] [Cannot obtain hardware information.]
Strace gives:

I compared the /sys/firmware/dmi/tables/smbios_entry_point to other hardware we use and it seems to be, that the Gen10 have a SM3 header for SMBIOS 3.0. I think Zabbix agent tries to read the tables as SMBIOS, not supporting SMBIOS 3.0 or not reading the entry point. Fallback to /dev/mem does not happen as it looks like. Dmidecode works fine.
