Description (partial)


Fabric datapath is down on a line card and all "show controller fabric crossbar" commands don't retrieve any output  as the CLI is waiting on the driver process (fab_xbar) which is continuously in running mode spinning in an infinite loop. Collection of show tech fabric is also timed out.

This is an extremely rare case and might be seen during card bootup of Tomahawk generation of cards. If the card boots up successfully with all interfaces up then this condition will not be hit.
