  Hmm, what is this "latency timer" exactly? Do I have to do anything else
besides using setpci to set register 40 to 0xff?

  Thanks. Unfortunately I don't have IDA pro, so I'll be unable to do it
myself, but in case you could provide the disassembled text, I would spend
some time to try to figure out what source 4 might be.

  I thought there might be some correspondence, since in my case there
really are unacknowledged interrupts (coming from source 4).
