Hi, Everybody, to be honest - I don't know at all, what this is about. But with my new DELL, I found the following lines in boot.log: <5>ACPI: DMI System Vendor: Dell Inc. <5>ACPI: DMI Product Name: Precision M2400 <5>ACPI: DMI Product Version: <5>ACPI: DMI Board Name: 0HT029 <5>ACPI: DMI BIOS Vendor: Dell Inc. <5>ACPI: DMI BIOS Date: 09/01/2008 <5>ACPI: Please send DMI info above to linux-acpi@xxxxxxxxxxxxxxx <5>ACPI: If "acpi_osi=Linux" works better, please notify linux- acpi@xxxxxxxxxxxxxxx ... and being a good guy, I do as is advised... :=)) The "acpi_osi=Linux" setting works better, as it makes the following error disappear: <4>mtrr: your CPUs had inconsistent fixed MTRR settings <6>mtrr: probably your BIOS does not setup all CPUs. <6>mtrr: corrected configuration. Nevertheless, the machine has (obviously) been properly working without the Parameter. My Linux is a SuSE 11.1 with vanilla Kernel 2.6.27.7-9-default. Have a merry christmas and a happy new year!!
