Bug ID: 1177288 Summary: Raspberry pi3 (model b) crashes with network gadget Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: coolo@suse.com QA Contact: qa-bugs@suse.de CC: guillaume.gardet@arm.com, nsaenzjulienne@suse.com Found By: --- Blocker: ---
I use the official Leap 15.2 Jeos image on a pi3b and have a USB network device attached to it (a very special one, https://www.fibrecode.com/fc602-usb-oabr-broadr-reach-100base-t1-stick.html) and it crashes the kernel pretty reliably with the following crash dump.

--- Comment #1 from Nicolas Patricio Saenz Julienne nsaenzjulienne@suse.com --- Is this a regression? Could you test it with tumbleweed and see if the issue remains?

--- Comment #3 from Stephan Kulow coolo@suse.com --- I can't say if this is a regression, I didn't use this setup before.

--- Comment #5 from Nicolas Patricio Saenz Julienne nsaenzjulienne@suse.com --- Sadly, RPi OS uses their own USB driver implementation, which we can't compare with.
Could you test your bug against the latest kernel: https://download.opensuse.org/repositories/Kernel:/HEAD/ARM/

--- Comment #10 from Stefan Wahren stefan.wahren@i2se.com --- Hi, i remember these kind of issue and AFAIK this should be fixed in the USB device driver. The best would be to reproduce this issue with a recent kernel and report the issue to linux-usb and the dwc2 & cdc_ether maintainers.
