in my case turns out, I have an Intel i5 which apparently doesn't

If your system doesn't even have multithreading, that warning on
resume from suspend must be a bug and is safe for you to ignore.
so I guess its as I suspected qubes isn't going to suspend well and
may break various things ??
Yes, the threading warning is unrelated to the sys-usb suspend issues
you were having. Did you try Daniel's suggestions up thread?
well Daniel said

This is a long-standing issue for some, resolved for some but not for
others at different times. See
https://github.com/QubesOS/qubes-issues/issues/4042
The situation has improved for me by getting kernel 4.19.43-1 from
qubes-dom0-security-testing. You could try the new kernel. (But note
that our problems might be a bit different, I never had a qrexec problem
when restarting sys-usb after resume.)
If you need to automate restarting of sys-usb because you can't avoid
this problem, you can add commands in
/usr/lib64/pm-utils/sleep.d/52qubes-pause-vms for suspend and resume,
e.g., qvm-shutdown sys-usb and qvm-start sys-usb. You might need to
qvm-kill sys-usb before suspend to get this to work reliably.

but curiously, AFAIK per dom0 uname -a I am already using
Linux dom0 4.19.43-1.pvops.qubes.x86_64 #1 SMP
but I shouldn't be on security-testing
otherwise I don't see much advantage to doing the 2nd paragraph and
maybe potential for badthings so ...
don't suppose it matter than my active kernel says #1 SMP but my
i5-6500 doesn't have SMT ? if xen.cfg says smt=off
maybe
the UEFI is smart enough to not show me what my CPU doesn't have, as I
saw no references to SMT multithreading at all ?
this is a Z170 Asrock UEFI
