Red Hat Bugzilla – Bug 127226
reboot locks without keyboard present
Last modified: 2015-01-04 17:07:36 EST
Description of problem:
reboot hangs, showing "Restarting system." in the last line on
console. It happens when keyboard is not present.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. reboot with keybard present, it will work.
2. remove the keybard, login through ssh, and reboot. It will work,
but Kudzu will run during the boot process.
3. Let Kudzu perform automatic system configuration.
4. Upon successfull startup, login through ssh and reboot. The system
will hang, showing "Restarting system." in the last line on console.
5. Reset button must be pressed to restart the system.
6. Every subsequent "reboot" will hang in the same maner.
7. Plug the keyboard back in, and "reboot" will work fine.
Installation was performed for "Server", with X but without KDE or
Gnome. X is not started - the system boots in console mode.

Attached is a portion of /var/log/messages with messages from the last boot.
The boot was preformed without the keyboard plugged in, so the first subsequent
"reboot" will hang.
One more thing: The first time "reboot" failed due to BIOS settings; once I
changed BIOS settings to ignore keyboard errors, the boot process controlled by
BIOS passes, but there is this problem.
I have ASUS A78X-MX-SE motherboard, with Phoenix v.6.00PG ACPI BIOS revision
If you boot the kernel with "acpi=off", then does the problem still
It still doesn't work - I have to press RESET to boot. I turned ACPI
off by changing my grub.conf to:
title Fedora Core (2.6.6-1.435.2.3)
kernel /boot/vmlinuz-2.6.6-1.435.2.3 ro root=/dev/md2 rhgb
title Fedora Core (2.6.5-1.358)
kernel /boot/vmlinuz-2.6.5-1.358 ro root=/dev/md2 rhgb quiet
/etc/grub.conf in my comment doesn't look correct (copy/paste
problem). In reality, the critical line "kernel ... acpi=off" is a
single line, not broken as in the comment.
I've had this problem and several others related to the
i8042 keyboard driver. Bug 124138 mentions going into
the BIOS and disabling "Legacy USB support", which I think
has fixed most of the problems including this one.
is this any better with the 2.6.10 updates ?
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
