    DQ35JO (1056) Intel Trusted Execution Technology

    gammern

      I just updated the bios from 0991 to 1056 on a DQ35JO m/b and found some issues when I enable "Intel Trusted Execution Technology". When it is enabled, the system slows down to a crawl. L1 cache throughput drops from 42106 MB/s downto 75 MB/s. Also noticed the same behaviour on a DQ35MP. Obviously the user will think the machine is hung during boot when it is operating at this kind of speed. This setting used to work fine under 0991. New bug introduced?
