Right, I was a little too enthusiastic here.

It's Alt-SysRq-R, Alt-SysRq-E, and so on. With little pauses between, to
give the action some time to work. Like, wait a little with the U (Unmount)
after the S (Sync). Or after the E (kill all processes) in order to give the
processes some time to save data, so the I (kill -9 all processes) does not
interrupt this.
