Yes, this is the case. I installed OpenBSD 6.7 i386 to the same hardware and there is no error in dmesg and X starts up without requiring machdep.allowaperture to be set. > The drm code in -current/snapshots has been replaced by a new port of > the linux 5.7 code so behaviour there may change. I tried the amd64 current/snapshot from August 8 and it has the same problem. I guess for now I can reinstall with i386 unless there is something else that I should try for debugging. I can provide whatever is needed. Thanks, Andy
