Comment:

 According to later comments in #5658, this is *not* a duplicate of 5658.
 This bug is in the OFW diagnostic for the keyboard (or in something that
 it depends on, like the EC or the keyboard processor).  It can be
 demonstrated in otherwise-working keyboards, on arbitrary keys (not just
 the Ctrl/Alt keys).  It does not appear to happen while in Sugar and
 !MiniTamTam.

 Mitch:  I wonder if adding a "view-lossage" type of display to the
 diagnostic would help figure out what's up.  Do we get a key-down and then
 no key-up?  Do we get two key-downs?  Do we get a serial garble?  Etc.

 We have with #5658 a high priority and pervasive flaky-keyboard problem
 (which seems to be hardware at this point).  Since this seemingly
 unrelated bug that shows up in the OFW keyboard diagnostic tends to
 confuse and/or mask diagnosis of the pervasive problem, I raised the
 priority of this bug.
