FWIW, just cherrypicking back 9e308e6a707bc29 (adding pcpu.h to one file) from the 4.16-12.0 branch sufficed to get it building and basically running. I also pulled back 324a27a734733 (DRM_SYSCTL_PRINT locking) and 148d05832cc12 (enable MSI) since they seemed like good things. Apart from a little trivial conflict resolution on the latter, it all Just Happened. In a solid 5 minutes of running it and testing a little video playing (on the system where 4.16 is stable aside from the videos), it hasn't blown up yet. I'll see if something happens over the next few days. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
