Humax hung but telnet still active

I have just experienced a Humax hang where it is not responding to the remote or front power button but I am still able to access the command line via PuTTY so I was wondering if there was anything that I could do to collect any useful diagnostics and/or unfreeze it without resorting to back power switch?

Nothing related to customised firmware appears to be running, no active recordings and HumaxTV process is only consuming moderate cpu

Correction - there are some CF processes in the list, some related to my attempts to use the webif but why are S90settop and autoschedule active

It's normal to have S90settop active but autoschedule wouldn't normally hang around (not the parent processes of run-and-gun and rcS)
