When PMU firmware is loaded in a non-JTAG Boot mode on a 1.0 Silicon, an error message ‘Error: Unhandled IPI received’ may be logged by PMU firmware at startup, which can be safely ignored. This is due to the IPI0 ISR not being cleared by PMU ROM. This is fixed in 2.0 and later versions of silicon.
