HP have recommended I disable ACPI in GRUB.<BR /><BR />They assure me that this won't have any impact on SIM or the ILO. However, does anyone know what the impact will be? Do I lose any kind of functionality by doing this?<BR /><BR />The hardware on the blades concerned is stable and I won't be making any changes for the forseeable future, if that helps<BR /><BR />Cheers<BR /><BR />Mick Tue, 27 Jan 2009 09:55:24 GMT Mick Ryan 2009-01-27T09:55:24Z https://community.hpe.com/t5/operating-system-linux/disable-acpi/m-p/4345334#M34989 All<BR /><BR />I have installed a new kernel version which generates some new error messages on startup.
