Description

With the system log set to show ~500 lines the system log tab will also show most if not all of the kernel boot messages (dmesg output).

Some lines in this output are not parsed as expected, making the log output table extremely wide and with unexpected wrapping/lack of wrapping.

See the attached images which are how parts of the following text log are being displayed by the System / General tab:

Once that line scrolls off the visible portion of the log it returns to normal.

Subject changed from Certain lines in kernel boot output can cause the default system log table to display in an unexpected manner to Hostname missing from logs in certain cases can cause the system log to display in an unexpected manner

Dug more into this and the problem is that somehow at boot the hostname was not being printed in the system logs on just that one installation during the early part of the boot sequence. Later in the boot sequence syslogd was restarted and after that point the logs contained the hostname.

I can't reproduce it on any other system in my lab nor can I replicate it on the same system when rebooting now that it's on the latest snapshot. It's possible it's something we already fixed but worth keeping an eye on for the next release just in case there is still a (rare) problem.
