Boot time slower on kernel 6.1 than 6.0


I have upgraded my kernel to 6.1 from 6.0 because 6.0 was EOL and wanted to be a bit up to date. When I boot into Manjaro on the 6.1 kernel, it would boot slower than the 6.0 kernel.
I do have a SATA SSD as my boot drive for my Manjaro install.
When I first startup my laptop, it would show my laptop logo, then it would show a black screen for a few seconds, and it would show my log in screen. The black screen stays for a few seconds longer on kernel 6.1 than 6.0.
Is this normal or is it just my laptop that’s the problem? If you would like more information, please let me know!

Startup finished in 2.998s (firmware) + 380ms (loader) + 2.359s (kernel) + 5.272s (userspace) = 11.010s reached after 2.954s in userspace.

systemd-analyze blame can also be helpful to see if there is a slow process at boot, but ten seconds to start doesn’t seem to be very slow. How many seconds lasted 6.0 to boot?

Here’s some extra information that may be helpful:

Seems TLP and Backlight take longer now. Did you check with 6.2 kernel series also?

I have not checked with the 6.2 kernel, but I can check and give you some information back about it if you would like to!
