When you say "Stable", you mean both kernel and Xorg?  Could you also
run xev on your stable box?

It looks to me like a keyboard bug.  Do you see any pattern, e.g. does
the left shift key produce one too?  Do the keys which do produce extra
scancodes form any particular shape on the keyboard?

Such bug should probably be fixed in the kernel, just like it is already
in atkbd.c for some keyboards.
