SPIN_LOCK_NOT_OWNED
Spin lock ownership violation for SPIN_LOCK_NOT_OWNED
SPIN_LOCK_NOT_OWNED is bug check code 0x00000010. Spin locks protect data at elevated IRQL and require strict acquire/release pairing. This bug check indicates that the current path did not own the spin lock state it tried to release or otherwise manipulate.
How to read it in a dump
- The failing stack should show the lock owner path or release routine.
- Check whether the driver mixed queued and ordinary spin-lock APIs or released a lock on an error path that never acquired it.
- IRQL and lock nesting are central to interpretation.
What to check
- Audit every acquire/release pair for the lock object.
- Check cancellation, timeout, interrupt, DPC, and unwind paths.
- Use Driver Verifier and special pool when memory corruption could have overwritten the lock object.

Dump evidence
Preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop. AllStat summarizes the condition as “this result”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order
- Run WinDbg
!analyze -v, then inspect the documented meaning of each parameter instead of relying only on the probably-caused-by line. - find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with spin / lock / owned.
- keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Do not repeatedly reboot a machine affected by this result before collecting the dump and event logs. Recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
