Package: linux-image-2.6.29-1-686 Version: 2.6.29-1 Severity: important --- Please enter the report below this line. --- After a few hours my laptop is on, the system suddenly becomes near totally unresponsive: the keyboard doesn't work (in particular, I can't switch to tty1 or kill X with Ctrl-Alt-Backspace), the mouse moves, but the clicks are processed with considerable delay (magnitude of minutes). The GNOME interface (panels, applets) are working, so I can see that the CPU usage is constantly to 50% (I'm on a two cores machine, so one core totally used and the other not).
I've tried to let the computer alone and without inputs for a couple of
hours, but nothing changed when I started again trying to bring it again
to normal work.
After reboot with Alt-SysRq-B, the syslog contains lots of messages like

I'm not able to understand what they mean. They seem to be sent out on
an average of once every one or two minutes, for the entire interval
during which the system is unresponsive.
I hope this annoying but to be fixed as soon as possible!
Thank you for your work on Debian and Linux. :-)
Regards, Giovanni.
