I'm seeing unexplained network behavior, such as sporadic inability to reach
beyond the subnet, passwords rejected for no apparent reason,
and SSH attempts constantly yielding that irksome man-in-the-middle attack
warning necessitating accepting new keys often (deleting entries in
~/.ssh/known_hosts file to start over again when trying to reach this
problematic Fedora 20 workstation).
But at other times, everything's fine.
I find no evidence of network intrusion or really anything else wrong with the OS, except this...
Nov 13 22:29:17 hostname /usr/sbin/irqbalance: irq 118 affinity_hint subset empty
The above message appears literally every 10 seconds or less in
/var/log/messages file. No idea what it is or means. Can this be at the
heart of what's troubling this installation?
