May be.
I usually see it as an "error".
My case: systemd sets sysrq on every boot to /lib/sysctl.d/50-default.conf kernel.sysrq value, which I usually set to 1. But after every systemd package update I have to edit 50-default.conf again, because somebody concluded that overwriting /lib/sysctl.d/50-default.conf during package update was the right thing to do. So, occasionally, when I need to do sysrq all I get is "This sysrq operation is disabled" error. So I swear a lot, reboot the box, change the sysrq mask and try to reproduce the problem. /* I became familiar with "sysrq_always_enabled=1" just recently. */
"This sysrq operation is disabled" is always bad news and is always not what I want to see.
