Description of problem:
At some point during boot the following messages start being output by the kernel
onto the console, and into the syslog:
Jan 6 02:54:28 click kernel: atkbd.c: Unknown key released (translated set 2, code 0x7f on isa0060/serio0).
Jan 6 02:54:28 click kernel: atkbd.c: Use 'setkeycodes 7f <keycode>' to make it known.
The machine in question does not have an AT keyboard attached, but uses a USB keyboard instead.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot the system with kernel 2.6.14-1.1805_FC5
Actual Results: atkdb.c error messages are printed once per second.
Expected Results: No such messages should be printed.
Also confirmed with kernel-2.6.15-1.1819_FC5, and confirmed that the messages
begin as soon as the kernel has started.
maybe try adding:
setkeycodes 7f 86
This is a BIOS emulation acting up. Best of all is to switch it off
in BIOS setup (sometimes called "USB Legacy"). The FC5 should have
default usb-handoff by now, which should accomplish the same effect,
but for some reason it didn't work here.
I am no longer seeing this problem with recent kernels from development.
The issue is resolved.
