OpenBSD 7.1 - hangs after userland upgrade on server hardware

Hi all,

I am totally stumped with issues while upgrading/installing 7.1 and I need
some help!

Server; Supermicro X10SLV-Q (Intel Q87 Express), Xeon E3-1280 v3, 8G RAM,
Mellanox 10G NIC

This server has been running OpenBSD flawlessly for years. I followed the
upgrade instructions and was able to reboot fine onto the 7.1 kernel (I
rebooted a couple of times on the 7.1 kernel in fact). However after I run
'pkg_add -u' to upgrade all of userland to 7.1, the machine started hanging
during boot.

The hang looked like an IO problem as it would always hang around the disk
setup stages.
I went into the BIOS and tried optimised defaults and failsafe defaults but
no luck..

I also downloaded a fresh copy and tried installing 7.1 from flash, however
the 7.1 installer also hangs. It hangs in the same place every time after
selecting 'done' to the networking config.
As I have a Mellanox card in here, I removed the NIC. but the hang
continues so its not that..

I get nothing to debug, it just freezes. I have reinstalled 7.0 which is
still working perfectly so this is not a hardware fault.

Is there anything I can do to increase the verbosity to see what driver it
is trying to load before the hang?

Other information, this is a totally headless machine, with a Xeon CPU
without any onboard GPU. It has a console connection with
console-redirection in the bios, and I have to set the tty params during
boot to interact over console. Otherwise everything else is standard.

Thanks for your time,
Best regards Andy.
