Hi Philippe,
seems we have some early boot problem with Dovetail on the BBB (while
qemu-arm is fine), see [1] vs. [2] (disabled Xenomai for [2], see [3]).
Do you happen to have such a target around? Or a reference config that
is supposed to work?

Yes, I have that one at hand, my Kconfig attached. No issue with booting
EVL on the latest Dovetail/5.10-LTS. I'll give a try to Dovetail+Cobalt
later today. (dtb issue in the CI?)

Just tried with PROVE_LOCKING, and DEBUG_DOVETAIL enabled. Still ok (evl
test suite passes as well).

Using wip/dovetail over dovetail-v5.10.y (.42 so far), bbb boots fine
with Dovetail fully enabled, Cobalt in stopped mode. Enabling the core
once booted, then running latency crashes in a fairly trivial way. It
looks like the paint is still wet there:

Confirmed, this is triggered by CONFIG_SMP which enables code expecting
the tick device to be enabled, although it could not be
enabled. Uniprocessor boots fine with the patch fixing the spurious call
to __request_percpu_irq applied.
With CONFIG_SMP, the core dereferences NULL in pipeline_set_timer_shot()
likely at the first host tick the in-band code attempts to program.
