If you are concerned about multiple OOPS case, I think an user app which logs from /dev/pstore to /var/log should be developed. Once it is developed, we don't need to care about multiple oops case and the appropriate number is two. - In case where system is workable after oops. The user app will erase an entry in NVRAM. And we can get the message via /var/log. - In case where system hangs up or panics due to the oops. Oops is the critical message and we don't need care about subsequent events. What do you think? > If you don't know what is the appropriate number ... then how will users decide? We should really give them some guidance ... > especially if there are odd problems[1] if they pick a number that is too big. You are right. There is no user app above right now. So, I was in stuck... But I understand I shouldn't have introduce efi_pstore_log_num.
