On my box it does not work w/o the c1e-apic one, but .... Unfortunately, with the c1e.patch on top of the apic.patch on top of the current mainline I get the same symptoms as with -next: - processes freeze - CPU loads are unreasonably high - things generally get stucked if I don't move the mouse or press keys Removing the the c1e.patch makes things work again.
