ERROR_GRAPHICS_INCONSISTENT_DEVICE_LINK_STATE
Why this is not a generic GPU failure: graphics inconsistent device link state
ERROR_GRAPHICS_INCONSISTENT_DEVICE_LINK_STATE, value 0xC0262436, is produced by linked when members of the linked set are in incompatible PnP or power states. The investigation should stay attached to linked-adapter PnP/power consistency and to the exact generation in which it was obtained.
The smallest evidence set
| Capture item | Why it matters |
|---|---|
| Rejected condition | members of the linked set are in incompatible PnP or power states |
| What to capture | member-by-member PnP and Dx states, transition history, surprise-removal and driver versions |
| Current graph state | lead adapter, chain members and their PnP/power transitions |
| Supporting trace | device-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering |
| Object identity | linked-adapter PnP/power consistency |
A/B test for the exact condition
- Capture the failing state. Record member-by-member PnP and Dx states, transition history, surprise-removal and driver versions.
- Bring all members to one known state and repeat the operation.
The comparison with ERROR_GRAPHICS_ADAPTER_CHAIN_NOT_READY is especially useful: ERROR_GRAPHICS_ADAPTER_CHAIN_NOT_READY is an aggregate readiness result without the explicit state mismatch.
Safe remediation
Repair transition synchronization and tear down the chain on member removal.
- debug-layer, ETW or driver diagnostics no longer report the rejected linked-adapter PnP/power consistency contract during the same scenario.
