Sorry for the delay in answering; I was on vacation most of last week. I'm not sure what's going on with the parport IRQs. If you think I need to look into that, let's start a separate thread for it. If there's work to do here, please cc: LKML too, since a parallel port issue could affect lots of people. I do not want users of 2.6.27 to have to change any parport_pc module parameters. If you had edit something in /etc/modprobe.d/, I think that's a bug I should investigate. Bjorn -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
