Bosko, I am seeing a very similar thing on my CURRENT system after applying your patch It's also when probing APM. I suspect it's not an issue with ACPI. It is also at least very similar to the crash I see when I add DISABLE_PSE to my kernel. Here is mine, as transcribed by hand from my IBM T30 with P4-M uniprocessor: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x1c fault code = supervisor write, page not present instruction pointer = 0x8:0xc06492a0 stack pointer = 0x10:0xc0c219a2 frame pointer = 0x10:0xc0c21b0e code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) kernel: type 12 trap, code=0 Stopped at vm_fault+0x240: cmpxchgl #edx,0x1c(%ecx) db> trace vm_fault(c102f000,c0000000,2,0,c07470a0) at vm_fault+240 trap_pfault(c0c21b9e,0,c00004d8,100000,c00004d8) at trap_pfault+0x1e3 trap(1bc40018,10,6fe40060,1c,0) at trap+0x2cd calltrap() at calltrap+0x5 --- trap 0xc, eip = 0x58de, esp = 0xc0c21bde, epb = 0xc0c21be4 --- (null)(1bf80058,0,530e0102,80202,5059f6) at 0x58de db> The kernel was cvsuped this afternoon and patched only with your patch. I had to panic twice to get a core dump and I have doubts about its validity. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
