Ctrl+Alt+Suppr did not work.
Ctrl+Alt+SysReq works only for key S "Emergency Sync complete". All
other keys in REISUB give "This sysrq operation is disabled.
I never heard that <ctrl> might be part of the sysrq combo.
Here on an x86 it's
0: press <alt>, keep holding
1: press <fn>-<print>, release <fn>-<print>
2: press the magic key, release it
3: release <alt>
But maybe you have most sysrq keys disabled: if you do a
cat /proc/sys/kernel/sysrq
you might see what currently is set (my guess: 16).

And careful: hitting 'c' in sysrq will crash your system .. :)
