is anybody else using this recent BIOS snapshot on the APU.1c: Build

The first re(4) interface isn't always recognized after reboot. I don't
know if it's related to the BIOS update since I didn't play much with
this board when I still had the BIOS beta from April flashed.
I've seen this re0-related problem multiple times with an OpenBSD
snapshot from April and also with a newer snapshot from September.
The kernel sometimes also freezes at ehci0 (see attachment).
So, at least my APU.1c device doesn't work reliably at all.
I was thinking about getting one of these (hopefully low-power)

Does anybody have experience with one of the boards from above on OpenBSD?
The X10SBA is a really nice board, although the C2550 based boards look nice
too. Per watt, the C2550 and J1900 are very competitive with the higher end
Intel CPUs. The X10SBA will be closer in price to the APU than the C2550 based
boards!
I've become afraid of UEFI BIOSes since legacy mode doesn't seem to work
with all of them (i.e., ASUS P9D WS).
Could you successfully boot a mainboard with one of the CPUs from above
on OpenBSD? Did you measure power consumption at idle?
I've never had problems with re0 and reboots on APU although you may be
right about the newer BIOS being problematic (or you may have some flaky
hardware?)
You should try and re-flash the April bios. I can send it over if you need
the image.
I've just reflashed the 4/5/2014 version which is now called "current
production" -- the same problem regarding re0. So yes, probably it's a
flaky NIC. Taken together with the flaky mSATA drive of some APU.1c
revisions and the unusually high operating temperature, I really can't
recommend this device. On the other hand, there were a couple of
positive reports regarding the APU.1c on misc@, so maybe I just had bad
luck...
Best regards
