Bug check 0x000001A3 (CALL_HAS_NOT_RETURNED_WATCHDOG_TIMEOUT_LIVEDUMP) occurs when a function call to a driver did not return within the watchdog timeout. The system live-dumped the state to diagnose the hang. The minidump identifies the driver that did not return. This is usually caused by: the driver waiting for hardware that is not responding (failing device), a deadlock condition between drivers, or a driver stuck in an infinite loop due to a bug. Fixes:
- Check the minidump for the driver that hung,
- Update the identified driver,
- If it's a storage driver: check disk health,
- If it's a network driver: check network adapter hardware,
- If it's a GPU driver: DDU clean install.
