Not really. I've got that fixed here. Apply this trivial patch:

extern int jail_timer_off;
void alarm_handler(int sig, struct sigcontext sc)
user = user_context(SC_SP(&sc));
if(!user && !kern_timer_on) return;
If that fails to fix it, then I'm interested in stack traces :-)

I'm having no problems with jail mode on 2.4.18. I just tried it on
2.4.19 and I get that panic. Stay tuned...
