I had exactly the same problem, using an AWE32 on IRQ 7. Disabling the lpt port on the mainboard doesn't help, since FreeBSD's driver still seems to get the wrong interrupt requests. I solved the problem by switching the lpt port to I/O polled mode, i.e. in your kernel config file, change the following line device lpt0 at isa? port? tty irq 7 vector lptintr to something like this: device lpt0 at isa? port? tty Then recompile and install your kernel and reboot. Switching the soundcard or lpt port to different IRQ numbers should also solve the problem, but that's not always possible, and I prefer having them on "standard" IRQs. By the way, switching the lpt port to I/O polled mode didn't have a noticable effect on printing speed.
