Description (partial)

Modems fall offline after an LCHA event and do not come back online on the protect. Prior to LCHA, user has changed the configuration on the OFDM channel.

This issue seems to happen when 'power-tilt' configuration is present on the controller IC config. With power-tilt config present, and OFDM channel reconfiguration on the controller followed by a LCHA to protect, modems fail to come online.
