Machine resets after nexus0 – took my SLR with 1s exposure time to make sure there's no more GOP output available :-( Haven't tried efi.rt.disabled=1 yet, since I had to spend some time to get the old kernel in place. non-booting kernel inquestion is custom r337804. Like Pete, I'm booting from a ZFS pool utilizing GOP, load_geli, zfs, aesni, nut my machine dosen't hang after "nexus0" but hard resets. The modules loaded don't influence the problem, even with only "kernel" (which is MINIMAL_config + very view devices/filesystems added) loaded, the machine resets after "nexus0". Will try efi.rt.disabled=1 tomorrow. Anyone intending to update a haswell/UEFI machine (Intel DH87MC in my case, with INVPCID microcode updated BIOS) could run into simialr situation I guess, so please make sure to be prepared... My first suspicion were side effects of r337715. But this is just a wild guess, haven't bisected anything yet. Thanks, -harry
