Firmware version is 2025-02-17T20:03:07, i also attach the full gzipped
dmesg, as long as a patch of extra traces used.
I did not specifically test other firmware versions for the timeout
issue (but i did for video output).

I use a custom one, attached.

No, i only use raspberry firmware/loader.

Just tried another monitor, and yes, timeout occurs without the patch.
Both monitors showed something when driven by firmware and
simple-framebuffer.
