There's nothing there that reaches out and grabs me:

  dev.cpu.0.%desc: ACPI CPU
  dev.cpu.0.%driver: cpu
  dev.cpu.0.%location: handle=\_PR_.CPU0
  dev.cpu.0.%pnpinfo: _HID=none _UID=0
  dev.cpu.0.%parent: acpi0

No, nothing there:

  interrupt                          total       rate
  irq0: clk                      184217768        100
  irq1: atkbd0                         554          0
  irq4: sio0                      31529039         17
  irq7: ppc0                            47          0
  irq8: rtc                      235761929        128
  irq11: xl0 ohci1               555868535        301

  Total                         1196776371        649
