Help text

By default, the Blackfin hardware errors are not exact - the error be reported multiple cycles after the error happens. This delay can cause the wrong application, or even the kernel to receive a signal to be killed. If you are getting HW errors in your system, try turning this on to ensure they are at least coming from the proper thread.

On production systems, it is safe (and a small optimization) to say N.
