Subject: NULL pointer dereference in ip6_datagram_dst_update

Hi,

While running 5.3.0-rc8 on my laptop, I receive an NULL pointer error when trying to use IPv6 (i.e. just browsing with Firefox). I have a desktop running the same version and kernel-config without problem (but different hardware). The laptop is using wireless (Intel AX200 iwlwifi).

Please let me know if you need more detailed information.

Thanks,

Raf.
