This may be completely unrelated, but it seems somewhat relevant: When pressing and holding a key during memtest86+ on an otherwise perfectly working T420, there are errors due to a different value being read than was written. Initially I thought my memory/motherboard is faulty and the keyboard pressure is triggering this, but the patterns are totally deterministic: the same key always does the same "damage" to the bits. Perhaps there is indeed something mapped into the memory... :-) -- Tomáš Janoušek, a.k.a. Pivník, a.k.a. Liskni_si, http://work.lisk.in/
