Yes, this is known.
See here:

Would be nice if this could get fixed.

Actually, it is fixed; the patch is upstream as commit
1b364bf438cf337a3818aee77d68c0713f3e1fc4

The patch was designed to fix the panic that occurred.  This warn on is
coming out of the sysfs code when we try to register a duplicate section
name.  The panic that followed is what the patch fixed ... but we still
get left with the warn on.

Yes, the crash is fixed, but still the warning is ugly.
Each time you load any module, this warning is filling up the log.
If you boot via serial console (like me) printing this warning with 9600 baud takes endless time (and you easily get up to 30 times this warning).
