As part of this thread, I've been gathering some additional diagnostics to aid the community in assessing my problem. I've created extracts from 6 of the main system logs in /var/log (specifically, syslog, messages, kern.log, dmesg, debug, and udev). Being a noob, I'm not very literate in reading or interpreting these logs. I don't want to inadvertently publicize information that could compromise my machine's security or open me to an attack. Can anyone advise on log information that should be munged or deleted prior to publication?

Thanks!

If you have an internet-exposed IP in the logs, I'd probably try to sanitize that. Other than that, I'd just make sure there are no passwords or anything.
