Subject: USB gadget regression on v6.4-rc1 and v6.1.28
Date: Fri, 12 May 2023 11:07:10 +0200	[thread overview]
Message-ID: <ZF4BvgsOyoKxdPFF@francesco-nb.int.toradex.com> (raw)

Hello all,
I recently did have a regression on v6.4rc1, and it seems that the same
exact issue is now happening also on v6.1.28.

I was not able yet to bisect it (yet), but what is happening is that
libusbgx[1] that we use to configure a USB NCM gadget interface[2][3] just
hang completely at boot.

This is happening with multiple ARM32 and ARM64 i.MX SOC (i.MX6, i.MX7,
i.MX8MM).

The logs is something like that

```
[*     �F] A start job is running for Load def…t schema g1.schema (6s / no limit)
M[K[**    �F] A start job is running for Load def…t schema g1.schema (7s / no limit)
M[K[***   �F] A start job is running for Load def…t schema g1.schema (8s / no limit)
M[K[ ***  �F] A start job is running for Load def…t schema g1.schema (8s / no limit)
```

I will try to bisect this and provide more useful feedback ASAP, I
decided to not wait for it and just send this email in case someone has
some insight on what is going on.

Francesco
