Reporting a consistent system-wide freeze followed by a Kernel Panic when attempting to use the "Add to Home Screen" feature in Safari. This issue has persisted across multiple recent iOS updates and leads to a device bootloop. Technical Details: The UI becomes entirely unresponsive for exactly 180 seconds. Analytics logs indicate a userspace watchdog timeout caused by SpringBoard failing to check in. Panic String: panic(cpu 0 caller 0xffffffff0422ccb9): userspace watchdog timeout: no successful checkins from SpringBoard (0 induced crashes) in 180 seconds Steps to Reproduce:
- Open Safari and navigate to any URL.
- Tap the Share icon.
- Select Add to Home Screen.
- The device UI freezes immediately. After 3 minutes, the system triggers a reboot.
Environment: • Device: 16PM
• OS Version: 26.4 RC and Beta 3 v1 • Feedback ID: FB22286846 (Full sysdiagnose and panic logs are attached to the original Feedback Assistant report). Questions: Is this a known regression involving the web clip background daemon, or does the 180s timeout suggest a specific database corruption within the Home Screen layout?
