If I'm not mistaken, the kernel doesn't actually function test the interrupt. In other words, you could have non-functional or misconfigured irq hardware, and the kernel wouldn't know. You might try using the polling driver and see how that works. If you're using the GENERIC kernel, disable the lpt0 driver and use lpt1 instead - just to test. If you're NOT using the GENERIC kernel, try the following in your kernel config - device lpt0 at isa? port? tty
