Bullshit. I dont even have an lp? driver. In fact, my experience is that the stray int 7 and the wd extra interrupt have the same cause. With different timings, I either 'gain' extra interrupts, and loose stray int 7's, or the other way around. >In your config file (/sys/i386/conf/MACHINE_NAME), change the lines: ># ># Interruptless printer driver ># >device lpa0 at isa? port "IO_LPT1" tty >to read like the following lines: ># ># Interrupt driven printer driver? perhaps :) ># >device lpt0 at isa? port "IO_LPT1" tty irq 7 vector lptintr >then just reconfig and recompile and reinstall your kernel.
