panic on resume in acpitz_setfan

Laurence Tratt
>Synopsis: panic on resume in acpitz_setfan
>Category: kernel
>Environment:
        System      : OpenBSD 6.1
        Details     : OpenBSD 6.1-current (GENERIC.MP) #1: Fri Aug 11 21:26:07 MDT 2017
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64
>Description:
    The following panic happened immediately after a resume (the second since
    the machine was switched on) on the Aug 11th snapshot:

      uvm_fault(0xffffffff81b3ff8, 0x200000003, 0, 1) -> e
      kernel: page fault trap, code=0
      Stopped at acpitz_setfan+0x8c:   movq 0(%rax), %rsi

      https://imagebin.ca/v/3Wmq884ayBSf

    This happened before the keyboard was reattached, so I couldn't get any
    further information from the panic.
>How-To-Repeat:
        Unknown
>Fix:
        Unknown

It turns out that this happens repeatedly on this machine. The precise
offset in the message changes but it's always of the form:

  kernel: page fault trap, code=0
  Stopped at acpitz_setfan+0x94: movq 0(%rbx),%rsi

AFAICT it never happens after the first resume, but only on a subsequent
resume (sometimes the second, sometimes the third etc.).

One thing that does occur to me is that this machine is fanless: the fans
are turned off in the BIOS. Maybe a null pointer is leaking in somewhere
because of that?
