Yes machine check was still occuring with latest kernel (2.6.16 with
patched mm subsystem - how I sed - I've searched gitweb to find all
changes from 20 March (when 2.6.16 was released)).
Then I start watching tlbex.c, because patch which was recomended (but
irrelevant as you say - and you were wright!) make mcheck occuring not
so often. So I make second changes :
