(only) when using Threading Firmware.

I use an unmodified Pyboard v1.1 and latest nightly firmware (v1.18-527-gea9a904b7 (2022-05-27) .dfu) downloaded from https://micropython.org/download/pybv11/, but I found it works incorrectly when using firmware with threading feature.

The manifestation of problems:
When I try to enter the safe mode or factory reset the filesystem, the pyboard would crash, and the green LED would be lit up unsteadily.
Or in another word, when the pyboard boot with USR button pressed, the boot would be failed. Unlike the manifestation described in http://docs.micropython.org/en/latest/p ... reset.html.

I tried the following comparison:
Using older version firmware: In v1.16 or earlier, it works correctly. But all newer release or nightly version have this problem.
Using firmware without threading feature: It works correctly in any version. (But I really need the threading feature.)

Could somebody tell me how to fix this problem? There are some new features in newer firmware which are helpful to my application, so I don't want to keep stay in v1.16

I can confirm that this fails with the release build V1.18 (threaded).

I have raised this ticket. The maintainers will doubtless fix this in due course.

It's already 1.19 release now, but the bug is still there.
Actually I raised a ticket before, but it seems to be ignored too.
