Is this problem new with 2.6.17.7? On the face of it, it looks
like every kernel should have this problem if you have other
devices on IRQ 4.
It's a recent problem, certainly.
Other devices (ehci_hcd:usb1 eth0 ohci1394) are already using
IRQ 4. lirc_serial doesn't request a shared IRQ unless you use
the "share_irq" module parameter. A request for exclusive use
of IRQ 4 will fail if it's already in use. So I suspect that if
you use the "share_irq" parameter, it will work.
This stops the errors coming up, I just get no data afaict. I'll spend
some more time trying to diagnose the problem.
Thanks,
Matt
