Sys Parameters, SMP_SPINWAIT
*Conan The Librarian
SMP_SPINWAIT establishes, in 10-microsecond intervals, the amount of time a CPU in an SMP system normally waits for access to a shared resource. This process is called spinwaiting. A timeout causes a CPUSPINWAIT bugcheck. The default value is 100000 (100,000 10-microsecond intervals or 1 second).
