Description of problem:
Periodically the keyboard stops working in X on my laptop.
(The mouse continues to function fine.)

'/etc/udev/rules.d//50-udev.rules' at line 25 applied, 'event1'

Oct 12 13:46:24 dash udev: removing device node '/udev/vcs63'

Unfortunately, with no easy way to reproduce the problem, it will be
tough to fix.
Hardware platform is a Toshiba Portege R100.
The problem happens with both kernel 2.6.5-1.358 and 2.6.8-1.521
you could do:
# rpm -e udev
as you do not require udev. This will remove the messages in
/var/log/messages, but not your problem.
Your problem may be a bad cable to your keyboard or s.th. like that.
Reassigning to component kernel, but I don't think, that it is a
I was able to reproduce the problem while the machine was booting,
so you were correct that this is a hardware problem.
Sorry for bothering you about it.
I'll try to close it out as NOTABUG, if I can.
