Hi,
I've just tried 2.6.0-test1 on my laptop. I get ACPI oopses when I change the CPU frequency through the ACPI proc interface:
Unable to handle kernel NULL pointer dereference at virtual address 00000240 printing eip: c0117243 *pde = 00000000 Oops: 0000 [#1] CPU: 0 EIP: 0060:[<c0117243>] Not tainted EFLAGS: 00010206 EIP is at acpi_processor_write_performance+0x173/0x200 eax: 00000230 ebx: cb77bb80 ecx: 01000000 edx: 00000200 esi: 00000001 edi: cccbfed4 ebp: 00000001 esp: cccbfeb0 ds: 007b es: 007b ss: 0068 Process autospeedstep (pid: 1231, threadinfo=cccbe000 task=cdc9a700) Stack: cccbfed4 01000000 00000000 00000001 00000000 01000000 c02b1b00 c02ae491 ce197660 01000000 00000001 c014bbde ce197660 cdd6e820 ced63060 cccdd400 00000001 00000060 cccbff00 ce197660 ce197680 cdc9a700 40018000 c011cf5c Call Trace: [<c014bbde>] handle_mm_fault+0xee/0x160 [<c011cf5c>] do_page_fault+0x13c/0x477 [<c014d448>] do_mmap_pgoff+0x5e8/0x710 [<c015988e>] vfs_write+0xbe/0x130 [<c01599b2>] sys_write+0x42/0x70 [<c010af7d>] sysenter_past_esp+0x52/0x71
