Reset via ssh on irresponsive machine

I have a machine I cannot physically access at the moment. Now this machine is irresponsive, in the sense that when I try to log in via ssh the output is

/bin/bash: Input/output error

and then the connection closes. I want to remotely reset the machine via echo 'reisub' > /proc/sysrq-trigger (which I believe should be possible since the kernel and ssh are still running). I have tried the following

ssh -T  "echo 'reisub' > /proc/sysrq-trigger"

but ssh is still trying to call /bin/bash and gives the same error. Is there any way to run the command directly (via ssh) instead of first calling bash?
