Public bug reported:
Hi,
I've noticed that the "Magic SysRQ" keys "E" and "I" (terminate / kill
all processes) have been disabled in all latest Quantal kernel.
Trying to use them spits to console a non amibiguous message : « SysRq :
This sysrq operation is disabled ».
This is vey annoying to me, as the keys often helped me out (and I
cannot figure out why they should be disabled).
