Description of problem:
When typing frequently the operating system does not seem to know when a key
has been released or pressed. This causes keys to appear to be stuck.
The problem does not occur in windows nor if I use an external USB keyboard.
It does not occur for every keystroke, but it does occur frequently.
I am using an IBM R32 Notebook (2658-N4M).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Type away till key gets stuck
Actual Results: The keystroke I pressed keeps repeating.
Expected Results: The key should have been released and only occured once.
Pressing the key again will fix the problem till it happenes again.
I've seen this too. This seems to be due to the APM BIOS causing keybaord
interrupts to get dropped whenever /proc/apm is read.
You'll notice a vast improvement if you shut off the battstat applet. If you
look at the date, you'll probably notice a great deal of clock skew.
Battstat polls /proc/apm once per second, which is kind of overkill, but there's
no simple way to change this AFAIK.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
