Technical Description
Cortex-A77 cores (r0p0 and r1p0) are affected by erratum 1508412
where software, under certain circumstances, could deadlock a core
due to the execution of either a load to device or non-cacheable memory,
and either a store exclusive or register read of the Physical
Address Register (PAR_EL1) in close proximity.
Remediation
Check the references section for vendor advisories and patches from arm. Update cortex-a77_firmware to the latest patched version.
