Problem with kernel major than 4.15.x

[Gilberto Nunes]

Hello again!

Right now, I booted my laptop with kernel
Linux version 5.2.2-050202-generic (kernel at kathleen) (gcc version 9.1.0
(Ubuntu 9.1.0-9ubuntu2)) #201907231250 SMP Tue Jul 23 12:53:21 UTC 2019

The system boot slowly, and I have a SSD Samsung, which in kernel 4.15,
boot quickly.
And there's many errors in dmesg command, like you can see in this pastbin

https://paste.ubuntu.com/p/YhbjnzYYYh/

The system get stuck for 5 seconds and then the X login screen appears!
Also, I get this message:
dmesg | grep stuck
[   40.231513] watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
[kworker/0:1:7]
[   68.231511] watchdog: BUG: soft lockup - CPU#0 stuck for 21s!
[kworker/0:1:7]
[  104.231513] watchdog: BUG: soft lockup - CPU#0 stuck for 23s!
[kworker/0:0:5]
[  176.239514] watchdog: BUG: soft lockup - CPU#3 stuck for 23s!
[kworker/3:3:593]

Which make the system freeze for a while and then return to normal!

Any help?
