  • 4b77061881 Pick up the return status code from the correct place now that we don't overwrite the parameter block until *after* the debug code. Michael Brown 2007-01-13 16:55:57 +00:00
  • 5817c9f114 When an UNDI API call fails, print everything there is to know about it. Michael Brown 2007-01-13 16:53:55 +00:00

  • 6a3c76c8e0 Always send EOI. We can't feasibly share interrupts (since we have no clue what the "previous" interrupt handler will do, which could range from "just an iret" to "disable the interrupt"), and that means that we have to take responsibility for ACKing all interrupts. Joy. Michael Brown 2007-01-13 14:45:26 +00:00
