I get these ACPI errors constantly every 5min or so in /var/log/messages 
and dmesg :

kernel: ACPI Error: SMBus or IPMI write requires Buffer of length 42, 
found length 20 (20090903/exfield-286)
kernel: ACPI Error (psparse-0537): Method parse/execution failed 
[\_SB_.PMI0._PMM] (Node ffff88061056cb00), AE_AML_BUFFER_LIMIT
kernel: ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM 

It's brand new HP DL380 G7 server with CentOS 6.2 with all updates.

Anyone know about these ACPI errors ?
