I had a very strange behavior of PXE when installing OpenBSd on my APU2 board.
If I set the kernel bsd.rd in the
etc/boot.conf file, the pxeboot is loaded, the kernel is loaded too, but the system loop-reboots.
If I do not set the kernel bsd.rd in the
etc/boot.conf file and at the boot> prompt enter it manually "bsd.rd" it just boots fine.
here's the output before the reboot
