AOP NMI FIQ
Reference imported from the supplied decoder v6.21 database. This entry has not been independently validated here. A matching log does not establish a failed component.
Supplied troubleshooting notes
Non-maskable interrupt in the Always-On Processor. The word after the pc= value is the AOP task that was running (for example power(1), rtk_ep_work(0)). One confirmed iPhone X case (rtk_ep_work(0), watchdog timeout) was the earpiece / front camera flex: the phone worked with it disconnected. iFixit's separate "AOP NMI POWER" entry (power-button cable or front camera) is a different string; no public source says they are the same. Likely: Earpiece / front camera flex (iPhone X case). Disconnect the earpiece / front camera flex and test: no restart = that flex. Then disconnect the other top flexes one at a time.
