 Replying to [comment:45 greenfox]:

 So it's not just an edge phenomenon.

 But only in the diagnostic. No one AFAIK has reported letter/number keys
 stuck in normal operation under linux. I'm thinking that this is an
 unrelated phenomenon due to a bug in the diagnostic. The far more serious
 problem (the subject of this ticket) is one in which a key "comes on" all
 by itself without being pressed, and then stays on until pressed and
 released. This is visible in both the diagnostic and normal linux
 operation.

 One more theory to throw into the fray: all the affected keys are in the
 lower left corner, more or less, of the keyboard. There's a big powerful
 magnet about an inch below that corner. Is it possible that the magnetic
 field is causing conductive parts to stick or be attracted (without
 knowing the technology of the keyboard, I'm poking in the dark here.) Can
 someone who is currently experiencing the sticky Alt or Cntl try putting a
 big hunk of steel over the magnet to divert its field and see if the
 problem changes in some way as a result?
