Bug Description
I'm currently running Gutsy on a Lenovo Thinkpad T61, and have been for two weeks, updating daily, currently up to date and running 2.6.22-7-generic #1 SMP on a core 2 duo system. About 10 minutes after every boot I get the following message logged to my gnome-terminal window:
Message from syslogd@isengard at Mon Jul 16 09:52:32 2007 ...
isengard kernel: [ 649.272000] Disabling IRQ #23
I assume 649 is the number of seconds from boot time, since that works out to be about the same time.
don@isengard:~$ grep 649 /var/log/syslog

AFAIK, it always logs the same IRQ. I'm not sure if this is causing random crashes in some programs. No noticeable loss of functionality when this gets disabled. I'm also completely willing to help troubleshoot this "live" over IM/IRC anytime.
The only way I know of to repro the error:
--Buy a Lenovo T61
--Install Gutsy tribe 2 and update to the latest packages
--Boot the installed system
--open up gnome-terminal before the message gets logged
--grep the_timestamp_
