Dear Dell PowerEdge users,

Installing Debian 9 with Linux 4.9.x and CentOS 7 with Linux 3.10.x on a 
Dell PowerEdge R730.

In both versions the Linux kernel reports the errors below.

kernel: ipmi message handler version 39.2 kernel: IPMI System Interface 
kernel: ipmi_si: probing via SMBIOS
kernel: ipmi_si: SMBIOS: io 0xca8 regsize 1 spacing 4 irq 10 kernel: 
ipmi_si: Adding SMBIOS-specified kcs state machine
kernel: ipmi_si: Trying SMBIOS-specified kcs state machine at i/o 
address 0xca8, slave address 0x20, irq 10 kernel: wmi: Mapper loaded
kernel: ACPI Error: No handler for Region [SYSI] (ffff8fbcdec42090) 
[IPMI] (20160831/evregion-166)
kernel: ACPI Error: Region IPMI (ID=7) has no handler (20160831/exfldio-299)
kernel: ACPI Error: Method parse/execution failed [\_SB.PMI0._GHL] (Node 
ffff8fb4df4a0eb0), AE_NOT_EXIST (20160831/psparse-543)
kernel: ACPI Error: Method parse/execution failed [\_SB.PMI0._PMC] (Node 
ffff8fb4df4a0348), AE_
kernel: (NULL device *): The BMC does not support setting the recv irq 
bit, compensating, but the BMC needs to be fixed.

Unfortunately, the Dell support told they can only escalate that to 
their software team, if this can be reproduced with an operating system 
installed by Dell, which are Red Hat Enterprise Linux and SUSE Linux 
Enterprise Server.

Is somebody on this list, who has a server with the operating system 
from Dell installed and could send me the Linux kernel messages? That’d 
be awesome!

Kind regards,
