USB issues with dwc_otg since a few 5.15 patch levels #5070

Describe the bug

Recently I've started to notice some flooding of the logs when using a USB WiFi dongle on a Raspberry Pi 3 B with a 32 bit kernel. I'm certain this did not happen in the past. I'm also so relatively certain that it's not related to the specific dongle, as I've tried 2 different types.

I'm building the kernel in a buildroot environment, basically with the default config as provided (bcm2709).

The logs show the following (this is a snippet, it keeps on going):

As you are building your own kernel. Can you narrow down where the problem started?

spockfish commented 2 years ago

Yeah I already thought that would be your first question ;-)

But agreed, I'll build a few kernels back and see when this started happening and let you know.

Thanks
