I have two different Macmini7,1 systems (the late 2014 and most recent Mac mini model). On one of them, I was using OpenBSD -current in April but haven't used the system or upgraded it to a newer snapshot. I purchased another similar system and went to install OpenBSD -current on it from the June 22 and found that I had a panic early in the boot process. The panic is from below which I hand copied. This is from bsd.rd but the panic is identical with bsd.mp as well. I did not get far enough to get a full dmesg with the recent kernels but could pull an old one as well if needed. Also, this is using EFI boot from a USB stick which has worked fine in the past.

Press press any key to reboot. rebooting... I believe the panic stems from revision 1.53 of acpiec.c. I can try reverting that commit on -current now and see if I can avoid the issue but there may be more to it than that. Any idea how to resolve this? There is also a separate issue that I will report in another message with "halt -p" causing a panic related to aml but that has been around for quite a while including in the April snapshot I am running on one of those systems. It isn't as important since reboot works fine. Bryan
