than happy to do some more testing.
As far as I remember, Fedora has it compiled in, but the standard is
"disabled". Look in /etc/sysctl.conf after "kernel.sysrq", and if
it's
set to 0 or not present, add "kernel.sysrq = 1" and do a "sysctl -p"
as root afterwards.
If a system hangs, the most important thing is to get all your data
written to disk, to minimize data loss. This is done by pressing "S",
after pressing and holding down AltGr+Prt(SysRq). An often cited and
well known combination (and easy to remember) is R-E-I-S-U-B.
Hope this helps!
