  1d:    e8 da e1 fe ff           call   0xfffee1fc
  22:    83 fd 01                 cmp    $0x1,%ebp
  25:    89 c7                    mov    %eax,%edi

  2b:    2b c1                    sub    %ecx,%eax

^^^ fail here?

  2d:    e0 02                    loopne 0x31
  2f:    03 47 10                 add    0x10(%edi),%eax
  32:    eb 2e                    jmp    0x62
  34:    8b 57 04                 mov    0x4(%edi),%edx
  37:    8d 4d ff                 lea    -0x1(%ebp),%ecx
  3a:    8b 00                    mov    (%eax),%eax
  3c:    8d 0c c9                 lea    (%ecx,%ecx,8),%ecx

Doesn't make sense.  There isn't a pointer reference here.  The following code
is nonsensical.

Looks like memory corruption, please post a disassembly of gfn_to_rmap() from
your kvm.ko.
