Eu tenho 2 servidores HPE Proliant DL360 Gen10 que são configurados praticamente iguais. Ambos executam o CentOS 7.5. As únicas diferenças são que um possui firmware e kernel mais recentes, na tentativa de corrigir esse problema.
dmesg
está relatando o seguinte repetidamente e o desempenho do servidor está sofrendo.

O HP iLO está reportando ~ 30C a menos que sensors
está relatando.

A interface HPE iLO informa que a CPU é de 55C ao mesmo tempo que a leitura dos sensores é realizada.
Quando executo sensors
, obtenho o seguinte em dmesg
:
[Oct12 11:46] ACPI Error: SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32 (20180313/exfield-393)

Eu atualizei para o kernel mais recente ( 4.18.13-1.el7.elrepo.x86_64
) esta manhã e isso também não ajudou.
