Thanks for your test, however it is my previous proposal. The latest one
is "[PATCH v2 0/4] firewire: core: call address handlers outside RCU
read-side critical section"[1]. The difference between two proposals is
just to use kalloc helpers instead of XArray for FCP handlers allocation,
thus not effects to your device.

Anyway, thanks.
