--- Comment #24 from Sérgio M. Basto <sergio-iCFKjj3otdHQT0dZR+AlfA@public.gmane.org> ---
BTW I started bisect kernel , but we have at least 2 phases , the first phase
the computer hangs but graphics still on [1], this week I hope starting second
phase and find the commit where really started EVO timeout, I tested binaries
of fedora first and it is between kernel-4.15.0-0.rc4.git4.1.fc28.x86_64 and
kernel-4.15.0-0.rc6.git0.1.fc28.x86_64 (build dates 22 dez 2017 and 01 jan 2018
) , that is the state of my investigation .

Thanks.
