SNAP-LCM4 controllers with newer clock chip may reset with Cyrano firmware

Applies To:

SNAP-LCM4

Versions Affected:

Problem was discovered in version: April 2007 through February 2008
Problem corrected in controllers manufactured beginning: March 2008

Symptoms:

Using a SNAP-LCM4 controller with the newer clock chip and Cyrano firmware could produce erratic behavior. On occasion the Cyrano kernel downloads successfully, but at other times it cannot. If the kernel download is successful, the controller may reset if an attempt is made to synchronize the controller clock with the PC clock.
