Disable CONFIG_USB_DWC3 until the driver problem is fixed.

NACK. That's not the way to go. If one test is failing in CI disable
that
test not really support which is for HW too.
Thanks, Michal
Hello Michal,
It is not that a single test fails. USB is completely unusable on the
board.
'usb start' leads to an immediate crash.
I am not applying any patches on SOM with HEAD and usb is partially
working.
Don't you see a crash when executing 'usb start'? What QEMU are you using?
I can agree that it is not super stable with upstream only patches but
that's
different story.
The problem already existed in v2021.01.
Any log?

Do you know of any QEMU/U-Boot combination where USB ever worked on
the board?
Why was this visible in CI in past and why this pops up now? What has changed? I don't think there was any change in QEMu regarding
USB but
I can double check.
We never started USB in the CI. With patch 6/6 of the series usb_bootdev_hunter() is invoked which
starts USB.
Did you push this to gitlab CI? Which test/py is failing there?
M
This is the failed job. https://source.denx.de/u-boot/custodians/u-boot-efi/-/jobs/955501
https://source.denx.de/u-boot/custodians/u-boot-efi/-/commit/636a4f4793d4d50...
The board failed to boot.
Best regards
