threaded memory test
Comment 2 Greg Nichols 2006-10-24 17:58:40 UTC 
The problem is with the test - it's attempting to use more memory than fits in
the virtual address space.   Changed Product to the Hardware Test Suite
Comment 3 Greg Nichols 2006-10-26 20:30:23 UTC 
Changed test to correctly identify this model as an i386 with more that 3GB of
physical memory.
