Thanks for the suggestion. I tried 6.11-rc7 which I am told includes
this patch. The first boot attempt was successful, but 4 subsequent
attempts ran into soft lockup again: it seems this patch makes the
soft lockup less reliable to reproduce but does not entirely fix it.

Noteworthy: after applying this patch, there seems to be slightly more
variability in where the soft lockup happens, instead of always in the
i915 driver probe triggered by udev. See attached boot logs for
details.
