Subject: [2.6.35-rc1-marc-00691-g7f0d384] Oops in dup_mm

Hi folks,

this morning I got a new Oops introduced. The system is overall 'slower', the
framebuffer is not re-drawn (nouveau, which works perfectly until 2.6.35-rc1-marc-00261-g03cd373)
and init is unable to send KILL and TERM when shuting down the machine. Shutdown
was further processes after hitting PWRBTN but still the box wasn't shutdown
completely.
