    Hi all,

    I took a quick look at yenta_sockets on the internet and they seem to be used to support pcmcia. You might want to cat >> /proc/irq and see if anything is attached to 19 (unlikely) or missing an IRQ (like pcmcia). If you have PCMCIA architecture you can run a lspcmcia (as a roootlike super being) and see if all the lights are still on.
