Maybe I'm missing a library or something.
The issue with this is the consistency.
one reboot I'll see it up higher in dmesg,
and then on another reboot nothing, then
maybe a few more reboots I'll see it down lower
in dmesg(like what I posted). As for fixing this
I'm not educated enough to go in and exactly know what
to change(one day hopefully, so I can contribute),
But I am willing to try a patch out to see if it resolves
the issue.
