(In reply to Michel Dänzer from comment #2) > https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/ > ?id=e97f12f359775de4fabfb507f836ebffa20f4986 should help for this. Thanks. imirkin warned me on IRC (wrt similar bug 104609 in nouveau) not to expect machine to reboot cleanly, so I'll be able to test it in a few weeks, which is when 4.15.x is expected to come to Fedora 27 anyway.
