Thanks Dave, I switched to the i915 kernel driver and still got the OOPS. I also continue to get the overlapping mtrr message. I am currently testing 2.6.13-rc2-git3. I have tried to run strace with hald, but cannot reproduce the problem this way. I am not sure I am invoking the command corrently. I have written to the hal developers, but have not received a response yet. Here's the current output: mtrr: base(0xe8020000) is not aligned on a size(0x3c0000) boundary mtrr: 0xe8000000,0x8000000 overlaps existing 0xe8000000,0x1000000 apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac) apm: overridden by ACPI.
