Description Emmanuel Galanos 2006-06-20 01:02:23 EDT
Description of problem:
I terminated the X server with Ctrl-Alt-Backspace due to bug #186689. Anaconda
drops to the console and terminates/unmounts everything and prints that it is
okay to reboot the system. However Ctrl-Alt-Delete does not work and the machine
needs to be power cycled. Not fun if the machine is being accessed via a kvm.

Version-Release number of selected component (if applicable):
FC 5 release installer.

How reproducible:
100%

Steps to Reproduce:
1. Terminate X server (or otherwise cause Anaconda to exit abnormally)
2. Try to reboot with Ctrl-Alt-Delete.

Actual results:
No reboot.

Expected results:
Reboot.

This works fine for me here -- is tty switching still working?  Also, you can
try sysrq as another option.
Comment 2 Emmanuel Galanos 2006-06-23 06:57:26 EDT
TTY switching still works. Sysrq also works.

The problem appears to be a kernel bug with ignoring right alt. Right alt also
is ignore in Anaconda.

left control-left alt-delete works
right control-left alt-delete works
right control-right alt-delete does NOT work (in Linux. Works in BIOS)

Comment 3 Chris Lumens 2006-06-27 15:48:47 EDT
Right control and right alt are different keys from the left ones, which means
they have different keycodes.  Linux doesn't trap those the way it does trap the
left ctrl and alt to cause a reboot.
