On FreeBSD with a port of the i915 driver from Linux kernel 6.7
(https://github.com/freebsd/drm-kmod/pull/332) we still encounter the
issue addressed by the workaround. I see a few commits following this
one that look like they may be related to this issue -- do you know if
there are required DSB fixes following this change?

We are of course continuing to move forward and will presumably bring
in fixes (if any) in due course, but if this was not yet reliable as
of Linux 6.7 we'll just keep the workaround in the meantime.
