Bug#795214: atkbd: keyboard events swallowed / spurious ones emitted on Thinkpad Yoga



Package: src:linux
Version: 4.1.2-1~exp1
Severity: minor

On my Thinkpad Yoga (20CD-0035GE), I'm occasionally seeing spurious
keyboard events; I'll describe it in the sequence I've discovered them:

* When playing supertux (a game heavy in cursor keys, space and control
  presses), I've observed keys hanging randomly, maybe once per five
  minutes -- eg. when crouching (by pressing the down key), tux would
  stay crouched even after releasing all keys, and only stand up when I
  pressed the down key again.

* printf debugging showed that the event was actually missing in the SDL
  event stream, but hinted at another "key up" event without a
  corresponding key down event I could find. The event there was
  SDLK_KP_6 (keypad 6 / right), a key not present on the keyboard.

  From this, I didn't look for missing events any more (which is pretty
  hard given its erratic nature), but looked for keypad 6.

* xtrace shows the keypad events as well (the one I've found there was a
  key down event of the keypad without a corresponding key up), they
  look like that there:

001:>:13c8: Event KeyPress(2) keycode=0x55 time=0x0498f33a root=0x000000d5 event=0x0b80000d child=None(0x00000000) root-x=634 root-y=224 event-x=632 event-y=160 state=0 same-screen=true(0x01)

* The keypad 6 event also showed up on xev after several minutes of
  mentally playing supertux, and looked like this there:

KeyRelease event, serial 40, synthetic NO, window 0xce00001,
    root 0xd5, subw 0x0, time 79559803, (171,206), root:(175,240),
    state 0x0, keycode 85 (keysym 0xff98, KP_Right), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

* I reached the limits of what I could easily debug at the edge of the X
  server, but roughly at the same time, I've seen events like this in
  dmesg:

[Aug11 21:20] atkbd serio0: Unknown key pressed (translated set 2, code 0xb9 on isa0060/serio0).
[  +0.000007] atkbd serio0: Use 'setkeycodes e039 <keycode>' to make it known.
[  +3.679327] atkbd serio0: Unknown key pressed (translated set 2, code 0xb9 on isa0060/serio0).
[  +0.000007] atkbd serio0: Use 'setkeycodes e039 <keycode>' to make it known.
[Aug11 21:23] atkbd serio0: Unknown key pressed (translated set 2, code 0xb9 on isa0060/serio0).
[  +0.000007] atkbd serio0: Use 'setkeycodes e039 <keycode>' to make it known.

Given that this whole situation at least spews out messages on kernel
level, I reckon this bug report is going in roughly the right direction
here -- of course, I can't rule out hardware or keyboard firmware
issues.

Is there any interface I can tap to gather further data or help tracking
this down?

Thanks
