The Documentation for sysrq-c certainly needs to be updated. If I am doing development on a system I like oops's. All of the information and nothing goes down. I can get at /proc/kcore etc. In a setting where I can't be Johnny on the spot and look at things a core dump is probably the best I can get. In that scenario panic_on_oops sounds good. As I read the current check it reads: If we are going to panic and not oops || panic_on_oops kexec_should_crash = true; Which seems a very reasonable implementation of policy. Eric
