From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: I am running a Thinkpad 600x using the yenti pcmcia driver and ibmtr_cs for my turbo token ring card 2 network adapter. What happens is like clock work every 55 minutes to an hour, my keyboard will no longer type, and my machine will be dropped from the network. The interesting part is, my machine can still use the mouse allowing me to reboot the box gracefully. I've tried booting linux with apm=off and that did not help either. How reproducible: Always Steps to Reproduce: 1.boot machine 2.run X for around an hour 3.will lockup Actual Results: I can run any given apps, I typicall am running x3270, netscape and xchat. After an hour, the keyboard doesn't type, the caps lock won't light when tapped. Try to ping from another machine, machine has dropped off the network. Expected Results: Machine should not drop from network and the keyboard shouldn't get dropped either. Additional info: I've tried this with 2 different NIC's on two different networks. I've tried just the turbo 16/4 nic with the same results
Can you try the following: rm /etc/cron.d/kmod service crond restart sounds like 1) cron is involved ('like clockwork') and the removal of a module could cause what you're describing.
this did not fix it. It occurred around the same time frame. I had xscreensaver locking my screen when I went to lunch, came back and was unable to type my password or switch virtual consoles.
looks like something assigned the tokenring card to a conflicting interrupt. Forced interrupt, ringspeed, and sramsize has fixed it.
