Re: Debugging crash in kernel module usbip-host

Greg,

Thanks for the feedback. I will update the kernel to 5.16 and verify the crash there too.

In the meantime, can you point me to where I can learn more about how these "stub" functions are generated?

Thanks,
Chuck

That is a very old and obsolete and known-buggy kernel, can you please
try 5.16?

thanks,
