Effect. Events 110, 111, and 112 are hardware errors reported by the Cyclone or
K10000 IPB chip and recorded in a common error counter. If more than 1000 of these
occur in a 19.2-second interval, the operating system shuts down the bus to all
processors and issues the ZIPB-EVT-BUSDOWN (101) event message.
Recovery. Normally, no recovery action is necessary. If the error continues to occur,
see Recovery Action Requiring Vendor Support on page 4-6.
111: ZIPB-EVT-IPBSENDERROR
