Basto --- Created attachment 141327 --> https://bugs.freedesktop.org/attachment.cgi?id=141327&action=edit the commit which start evo timeout And result of git bisect start v4.15-rc6 ead68f216110 is [1] This is the commit when switch graphics at boot startup starts to fail, I'm thinking in the revert it in kernel-4.15.0-0.rc6.git1.1.fc28 which already have the good interrupts, to see if I can boot correctly again . Or should I seek for commit that fix delivery interrupts ? what do you think ?
