I've been having trouble getting 6.x, 7.x and 8.0 to boot on a Lenovo ThinkCentre M-series, model 6081 AG1. The system panics on boot, what seems to be as soon as it goes to boot the kernel (it loads the kernel and modules like acpi.ko fine)... System is running the latest BIOS (2KRT50AUS) from 22 July 2008; we have successfully booted Windows and Linux on the same system, and it has survived several hours of memtest'ing. The panic (manually transcribed, so I hope I haven't made any typos) as seen from the 200807/i386 snapshot CD: /boot/kernel/acpi.ko text=0x54624 data=0x2640+0x182c syms=0x4+0x8b70+0x4+0xbe09] GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fatal virtual address = 0xf000ff53 fault code = supervisor read, page not present instruction pointer = 0x20:0xf000ff53 stack pointer = 0x28:0xc1421f0c frame pointer = 0x28:0xc1421f9c 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 () [thread pid 0 tid 0 ] Stopped at 0xf000ff53: *** error reading from address f000ff53 *** db> bt Tracing pid 0 tid 0 td 0xc0c837c0 trap(c1421fa8) at trap+0x66f calltrap() at calltrap+0x6 --- trap 0x9, eip = 0x3fbb, esp = 0xfd2, ebp = 0 --- db> sh reg cs 0x20 ds 0x28 es 0x28 fs 0x8 ss 0x28 eax 0xf000ff53 ecx 0x9 edx 0xa ebx 0x9 esp 0xc1421f0c ebp 0xc1421f9c esi 0xc1421fa8 edi 0xc0c837c0 thread0 eip 0xf000ff53 efl 0x10286 0xf000ff53: *** error reading from address f000ff53 *** db> Is there any additional information I can provide from the DDB prompt that may help tracking down why this machine is unable to boot (I have included the output from backtrace above, but it does not appear to help much...)?
