            Bug ID: 44622
           Summary: winebus.sys crashes in IoCompleteRequest() for IRPs of
                    unloaded hidclass.sys driver (race condition)
           Product: Wine
           Version: 3.2
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: joseph.kucia at gmail.com
      Distribution: ---

hidclass.sys can be unloaded when winebus.sys irp_queue is not empty.
IoCompleteRequest() crashes when CompletionRoutine is called for the unloaded
driver. ntoskrnl should probably handle this case better.
