This shouldn't happen, but I've got a Linux computer with the clock frozen at an hour ago and unsaved work that I can't access Does Magic SysRq always work? Am I doing it wrong? (Alt + PrtSc + key, eg REISUB) A website took out Firefox's JS process, which coincidentally manages Gnome's UI. System becomes slow, eventually locks up. I suspect that a process goes mad and eats all memory. Machine has fallen off network because of this, so no SSH for me Any of the console access from X keys don't work. Mouse pointer no longer moves. CPU fan is making the one core is maxed out noise Any suggestions for getting my machine back without damaging the SSD gratefully received - disk access light solid. Any potential diagnostics for after the fact (I'm assuming the machine's non-responsive to new connections) also welcome Thanks Stewart
