- KbdDispatch: Set Status vice IoStatus.Status for all branches of switch. Use break instead of goto intcontfailure.
The previous code would set Status to what ever was in the IoStatus.Status of the IRP and return that Status.
Some times this would be STATUS_PENDING, which IIRC is a no-no.
This caused the kbdclass to enter into a wait that would never be satisifed hence blocking the keyboard thread.
This should fix the failure of keyboard input bugs.
