Hi Lucas,

Given that I'm not having a great success at reproducing the issue you
mentioned, could you test the following patches to see if it improves things?

Thanks!
Maxime

Unfortunately I'm missing a cable and will only get it back during the
week-end, so I cannot test before early next week. However I'm Ccing
Ryutaroh Matsumoto who could also reproduce it. Maybe he is in a better
position to test this (@Ryutaroh: I bounced the patches to you).

Should I apply PATCH RFT 0--2/2 to
https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.7.tar.xz
or some branch of someone's git repo?

On my Raspberry Pi 4B 8GB model, all versioins up to upstream 5.10.6
fail to boot on USB MSD due to changes to the USB handling by raspi
introduced in 5.10 series, and failed to boot from an SD card up to 5.10.3
or so. No working WiFi connections neither on my raspi 4b.

I am unsure if I can test the patch reliably. But I will try it within a few days.

Best regards, Ryutaroh

We just had another lead on this one and that patch doesn't seem to
prove useful to fix it, so it's probably better to hold off the testing
at this point

Thanks!
