Created attachment 1455394 [details] boot log I recovered the boot.log using a live cd. No error detected.
After some tests i found the guilty: the rtl8188eu driver. After removing the dongle the system works.
The problem is still present in 4.17.3 kernel.
This issue has also been reported on ask.fedoraproject.org: https://ask.fedoraproject.org/en/question/123443/kernel-417-wifi-usb-restarts/
Today I updated the system and I tried kernel 4.17.5: it worked well. Then I tried again 4.17.2 and 4.17.3 and..... they also worked. So the bug is gone but i don't know which component was bugged, for sure it has something to do with wi-fi userland and rtl8188eu driver. I also found a post in the kernel bugzilla that i think is related to this problem: https://bugzilla.kernel.org/show_bug.cgi?id=200301
