Hello John, thanks for your efforts to pin down the issue. It's unfortunate that usb_drv just dies on your Yoga because it's essential for report_dump to work.

In the past, the cause was often misaligned pointer (incl. the stack pointer) in combination with FPU/SSE instructions, but it would be a wild guess in your case and also does not help to pin down the location in code. Could you share some more information about the hardware specs of the Yoga? For example with a Live Linux sudo lspci -vvvnn sudo lsusb -vvv sudo lshw -sanitize Also, I suggest to move the bug hunt to a dedicated issue on GitHub [2].
