Following up on my last mail about the reform2, I have now swapped out 
the CPU module for the older and better supported i.mx8mq SoC and i 
works better but NetBSD 10 hangs hard while the kernel is attaching 
devices, so hard in fact that I can't even get into ddb via the 
three-finger-salute on the keyboard (probably because the usb keyboard 
hasn't been detected yet) nor by sending a break on the serial debug 
console.

I'm here using a u-boot that has been specially patched for openbsd 
(although the one not specially patched also hangs in the same way). I 
also tried using the dtb command in boot to load it before booting with 
the same results.

The dmesg up to the hang follows, what can I do now?

Press return to boot now, any other key for boot prompt
