iPhone 18 Pro panic reboot after "Try Face ID Again" PSD PANIC "timed out on PMGR"

Hi everyone,

My brand new iPhone 18 Pro (iOS 27.0, build 24A437) froze and rebooted on its own.

Steps:

Opened an app protected with "Require Face ID".
Face ID failed.
Tapped "Try Face ID Again".
The phone stopped responding to touch and rebooted to the lock screen a few seconds later.

A panic-full log was created. The panic string is:

PSD PANIC (0xdeadfeed) : PSD_PANIC_TYPE_FATAL : Assert ID: 0x22 ps:64 timed out on PMGR! : 14 Awake SBDs @AppleSoCErrorHandlerT8160.cpp:2260

Unlocking from the lock screen works normally, and there are no other issues so far.

Questions:

Does anyone with the same Face ID reboot have the same panic string ("ps:64 timed out on PMGR")?
Has anyone gotten a replacement, and did the new device still have the issue?
Is this confirmed as an iOS 27 software bug?

Thanks

iPhone 18 Pro, iOS 27

You’re not the only one seeing this. The same sequence — Face ID fails in a protected app, “Try Face ID Again” is tapped, then the iPhone freezes and reboots — has been reported by other iPhone 18 Pro/Pro Max users.

I wouldn’t put too much weight on the exact “ps:64 timed out on PMGR” panic string by itself. I haven’t seen reliable information showing that everyone experiencing this Face ID reboot gets the same panic entry.

There have also been reports of affected devices being replaced, but that doesn’t confirm whether the cause is hardware or software. So far, Apple hasn’t publicly confirmed this specific behavior as an iOS 27 bug or announced a fix.

Since Face ID works normally from the lock screen and the reboot seems tied to this particular retry sequence, I’d keep the panic-full log and report the issue to Apple rather than deliberately reproducing it again. It’s also worth watching for the next iOS update.

Warum ärgerst du dich damit herum ? Fehlersuche bei einem brandneuen Gerät ist nicht deine Aufgabe.

Du kannst jedes Apple Gerät innerhalb von 14 Tagen nach dem Kauf zurückgeben.

Das solltest du tun. Unverzüglich.
