parm:           trypci:Setting this to zero will disable the default scan of the interfaces identified via pci (bool)
parm:           tryplatform:Setting this to zero will disable the default scan of the interfaces identified via platform interfaces besides ACPI, OpenFirmware, and DMI (bool)
parm:           tryacpi:Setting this to zero will disable the default scan of the interfaces identified via ACPI (bool)
parm:           trydmi:Setting this to zero will disable the default scan of the interfaces identified via DMI (bool)
parm:           type:Defines the type of each interface, each interface separated by commas.  The types are 'kcs', 'smic', and 'bt'.  For example si_type=kcs,bt will set the first interface to kcs and the second to bt (string)
parm:           addrs:Sets the memory address of each interface, the addresses separated by commas.  Only use if an interface is in memory.  Otherwise, set it to zero or leave it blank. (array of ulong)
parm:           ports:Sets the port address of each interface, the addresses separated by commas.  Only use if an interface is a port.  Otherwise, set it to zero or leave it blank. (array of uint)
parm:           irqs:Sets the interrupt of each interface, the addresses separated by commas.  Only use if an interface has an interrupt.  Otherwise, set it to zero or leave it blank. (array of int)
parm:           regspacings:The number of bytes between the start address and each successive register used by the interface.  For instance, if the start address is 0xca2 and the spacing is 2, then the second address is at 0xca4.  Defaults to 1. (array of int)
parm:           regsizes:The size of the specific IPMI register in bytes. This should generally be 1, 2, 4, or 8 for an 8-bit, 16-bit, 32-bit, or 64-bit register.  Use this if you the 8-bit IPMI register has to be read from a larger register. (array of int)
parm:           regshifts:The amount to shift the data read from the. IPMI register, in bits.  For instance, if the data is read from a 32-bit word and the IPMI data is in bit 8-15, then the shift would be 8 (array of int)
parm:           slave_addrs:Set the default IPMB slave address for the controller.  Normally this is 0x20, but can be overridden by this parm.  This is an array indexed by interface number. (array of int)
parm:           hotmod:Add and remove interfaces.  See Documentation/IPMI.txt in the kernel sources for the gory details.
parm:           bt_debug:debug bitmask, 1=enable, 2=messages, 4=states (int)
parm:           smic_debug:debug bitmask, 1=enable, 2=messages, 4=states (int)
parm:           kcs_debug:debug bitmask, 1=enable, 2=messages, 4=states (int)
parm:           force_kipmid:Force the kipmi daemon to be enabled (1) or disabled(0).  Normally the IPMI driver auto-detects this, but the value may be overridden by this parm. (array of int)
parm:           unload_when_empty:Unload the module if no interfaces are specified or found, default is 1.  Setting to 0 is useful for hot add of devices using hotmod. (bool)
parm:           kipmid_max_busy_us:Max time (in microseconds) to busy-wait for IPMI data before sleeping. 0 (default) means to wait forever. Set to 100-500 if kipmid is using up a lot of CPU time. (array of uint)

needs to be replace for fix this issue.

How old is that server ?

Sometimes PSU have voltage issues when they get cold or warm as they are worn out. Re-seating may help or reset the error but it is better to get HP to look at it as not wise to fool around with power components (especially if it can be fire, safety and health hazard).

Hi,

Good day!

These messages doesnt seems to be harmful.

What we see is the messages are related to power monitoring and it could be a BIOS issue which should be addressed by BIOS update. 

These error messages can be avoided by blacklisting the "acpi_power_meter" module causing the IPMI region to be used.  The acpi_power_meter module seems to be causing this issues, The messages are a sign that some power management features may not be usable and these messages can be considered informational and not a harmful error and can be ignored.

# echo "blacklist acpi_power_meter" >> /etc/modprobe.d/hwmon.conf

You may try updating BIOS and check.

Thank you
