Hi,
during boot up, I am trying to find where the kernel takes more time
to do actions (is slower ?).
I looked at dmesg and found some places where it takes more time, but
not sure if this is normal :

Not sure if it is normal or not...maybe it's just normal behavior or
cannot get any faster...
Thanks for reading.
Cheers
