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
Steps to Reproduce:
2.run X for around an hour
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.
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:
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.
