      Alter:

      I don't see any problem with PATA + ATAPI part
      But I see a problem, which may cause USB keyboard/mouse freez:

      AtapiInterrupt(base): set CHECK_INTR_IDLE (2)
      AtapiInterrupt(base): exit with status 0x0
      (ntoskrnl/ex/work.c:351) EX: Work Queue Deadlock detected: 1

      unexpected, 1st chance

      It seems to in in USBOHCI.
      I mean using Work Queue API inside USBOHCI ISR.
      Uniata doesn't use Work Queues at all, since this is not allowed on high IRQLs.
