My system crashed regularly on usage of graphical Browsers. Other people had the same issues: https://marc.info/?l=openbsd-misc&m=150916174632762&w=2
After searching for the problem I found the solution in DragonflyBSD and ported those changes to our inteldrm: https://www.mail-archive.com/[email protected]/msg157533.html The patch fixed the issue not only for me, but for at least two other users. Could someone please apply those changes to our inteldrm?
