That's the real kicker. I can't. You upgrade above some specific
version, and you can't then go back below it. The "working" one was
below that threshold. But, IIRC I *never* got SmartOS to run on this
board. Only Solaris 11.
I know you said back then you tried to disable ACPI in the bootloader
and it didn't work for you, but interestingly this week we had on
OpenIndiana mailing list user with a similar problem (or a symptom at
least) on a fairly recent system : https://pasteboard.co/Hv2lxJs.jpg.
He fixed it by disabling ACPI in the bootloader. Here's the discussion:

Not sure what is the right approach to this on SmartOS though.

BIOS.
I have messed about with debug mode and kmdb, but I didn't get very
far. When I initially reported the issue there seemed some interest in
fixing it, but about two days later Meltdown and Spectre surfaced.
I would think that H110 and Skylake is far from an uncommon combination,
and obviously the ideal solution for everyone would be to fix it. It's
clearly something in the SunOS kernel. Linux, FreeBSD and OpenBSD all
work perfectly. Solaris 10, SmartOS, Tribblix and OmniOS lock completely
early in the boot process. Solaris 11.3 boots if only one core is exposed.
If any kernel genius is interested in investigating, please talk to me.
