Dump evidence for KERNEL_STORAGE_SLOT_IN_USE

For KERNEL_STORAGE_SLOT_IN_USE, 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 “KERNEL_STORAGE_SLOT_IN_USE”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.

Analysis order for KERNEL_STORAGE_SLOT_IN_USE

  • Run WinDbg !analyze -v, then inspect the documented meaning of each KERNEL_STORAGE_SLOT_IN_USE 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 kernel / storage / slot / in / use.
  • For KERNEL_STORAGE_SLOT_IN_USE, 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 KERNEL_STORAGE_SLOT_IN_USE before collecting the dump and event logs. For KERNEL_STORAGE_SLOT_IN_USE, recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
