hi, I've tried this patch, here's what it produce as log: From the linux kernel: [ 0.452071] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.480085] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.788222] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) And: [ 0.308271] mtrr: your CPUs had inconsistent variable MTRR settings [ 0.308272] mtrr: probably your BIOS does not setup all CPUs. [ 0.308273] mtrr: corrected configuration.
And I think my CPU is covered by your patch: CPU is Fam 0Fh rev.F or later, using TOM2WB instead of MTRR above 4GB
Also, without pci=nocrs Xorg don't initialize.
I've attached the full log(compressed with xz)
Thanks a lot for working on this.
Denis.
