Hm. I haven't seen those before. Did you try reseating the RTC and

fx isn't particularly difficult. I still think OpenBSD's partition
editor (not the disklabel editor--the partition editor) takes the cake
for being the biggest PITA. It won't even let you know about

That's what's making me think your memory might not be properly seated.
Bad cache can also cause this.
