Description (partial)

When power up/down, OIR insert/remove linecard or after SSO or supervisor failover, EBUS_SEQ_ERROR may be seen and the in some scenarios the device gets reset.
This could be triggered if the fabric mode of the newly brought-up line card
 is different than the default mode.

This happens only in VSS setup following a SSO failover. The problem can also be
 seen during OIR of a new linecard.
