From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
Lots of messages "pc_keyb: controller jammed (0xFF)." displayed during kernel 
This problem was found on really legacy free system(Without SuperIO, Keyboard 
Controller) only.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Take a legacy free system(Without keyboard controller)
2.Put Red Hat Linux cdrom in CD-ROM drive and boot from it
3.Lots of proble messages displayed

Actual Results:  Lots of messages "pc_keyb: controller jammed (0xFF)." 

Expected Results:  No error messages should be displayed.

Additional info:

This might caused by Kernel doesn't check the keyboard controller whether 
exist or not, If keyboard controller is not exist, kernel should skip all 
keyboard controller access and don't treat is as error. ALL Port 60/64 access 
should be emulated or skipped.

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/
