Yes. I know and understand what you said! ;-) I only added that it might not be a hardware bug - but a miss-programming or interpreting of the hardware, introduced in one of the last 2.4.1x kernel! I never got this in the past and now I get it on ALL machnines!
Or was this debug-message introduced in a 2.4.x kernel and this situation was simply ignored?

I bet if you look in parport code you'll see that LPT > ints get silently ignored if there's nothing to do. It just thinks: "whee, > printer int, let's look at LPT ports... hmm, strange, printer is ready, > nothing to do... oh well, iret". > -- > vda
