Message from syslogd@schmauck: Disabling IRQ #19

[Daan]

Hi all,

For long time I've been getting messages in terminals about IRQ #19:

daan@schmauck:~$ 
Message from syslogd@schmauck at Mon Mar 16 18:29:27 2009 ...
schmauck kernel: [  987.362621] Disabling IRQ #19
daan@schmauck:~$

I do not note anything going wrong that seems directly related with this message, but I would like to know what it measn and how it can be fixed.

Here's some lines from dmesg:

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.
