In approximately 1 in 5 1 hour runs of BurnInTest 5.1 or 5.2 on a particular class of hardware I get the error "No operations reported in timeout period" for either the CPU Maths or SIMD test with a negative number of operations reported. E.g:
Code:
Test Name                   Cycles   Operations      Result Errors   Last Error
              CPU - Maths   3        -1996516420     FAIL   1        No operations reported in timeout period

An old thread http://www.passmark.com/forum/showthread.php?t=474 reported a similar error and it was suggested that this was a BIT bug and was fixed in a new version. I assume that new version was 5.2. I see these errors with 5.2 - is there a known bug? (I want to check before I start chasing hardware/platform issues.)
