Note that there are no fault logs from the DMAR blocking invalid DMA
access.  Look at the release 10.1 logs, where there are lines like

DMAR0: <unknown dev>:pci1:0:0 fault acc 0 adt 0x0 reason 0x5 addr 0

and which I cannot find in your CURRENT kernel dmesg. I would say that
the machine is fine, at least WRT the boot sequence.

Then, I looked back at the previous logs from you, and both logs I
have say 10.1-RELEASE-p6 in the herald. You overwrite the logs, so
I cannot recheck the history, but it seems that you did not tested
stable/10 ? There is currently no difference in DMAR code between head
and stable/10.
