+    ide: cancel pending callbacks on SRST
+
+    The SRST implementation did not keep up with the rest of IDE; it is
+    possible to perform a weak reset on an IDE device to remove the BSY/DRQ
+    bits, and then issue writes to the control/device registers which can
+    cause chaos with the state machine.
+
+    Fix that by actually performing a real reset.
+
+Yup. Mark Cave-Ayland pointed this out to me. I have a patch ready for it:
