[solved] journalctl: "kernel: [217B blob data]"

Sep 26 09:15:06 archlinux kernel: [217B blob data]

Can't figure out what that's supposed to tell me in my log (journalctl). Any hints?

edit: This might possibly have meant: "Your nvidia kernel module version does not match the installed stuff". Or something else... anyway, it's gone after a reboot, can't say for sure what it was. How do I figure a relation like this out without random trial + error?

Thanks!

I have similar messages in my journal, and my system runs well. In my opinion you can safely ignore it.

kernel: [117B blob data]
NetworkManager[197]: [162B blob data

65kid is right. journalctl tries to detect if some journal data is binary rather than text, and if so, it shows the "blob data" output instead of the message. Its heuristic for telling the difference seems a little buggy, and hides things that could be shown sometimes. The "-a" flag disables this (and would then print actual binary data as well if any ever appeared).

Thanks, found the messages I've been missing! That heurism really seems to categorize about everything that has many numbers in it as "binary", even if it's just a memory address or even date / time that makes up most of the message.
