I have been watching posts on this list and see that many users employ netconsole. My netconsole is native to the 4.18.7 kernel, and works perfectly for about 13 sec ( 12.954965 last attempt) after boot. It then hangs. 709 lines are transmitted before the hang. If I examine /var/log/messages there are a lot of systemd messages printed immediately after the last successful kernel message that was transmitted by netconsole.
I thought that anything that went to printk also went to netconsole. But netconsole does not appear to be awakened after the first systemd message is logged. I have examined netconsole.c and printk.c, but am overwhelmed and am not able to determine what triggers netconsole. I feel that the trigger may be negated by systemd or some other part of system startup. I am running opensuse 42.3 and have not had any replies from their lists. I feel it is that the native netconsole is not a component of their distribution so it is my problem.
I can forward any data desired output from dmesg, netconsole, or /var/log/messages. Any assistance would be greatly appreciated.
Don
