Created attachment 286225 [details] screenshot of panic stacktrace Apologies if this is this wrong place to raise this bug. I upgraded my ubuntu system to 5.3.0-24, and now get always-reproducible panic on boot entering runlevel 2 in skb_get_hash_perturb. this using version 8042-0ubuntu1 of backport-iwlwifi-dkms. the same bug does not appear on 5.3.0-23. I was unable to get a text version of the stacktrace, but i took a picture - hopefully this is useful.

Re-filed as https://bugzilla.kernel.org/show_bug.cgi?id=205839
This is already fixed here: https://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git/commit/?id=7eb087cb342f2c1a351b32366738898015c95cd8 and also backported to the 4.19 branch. I am missing the Ubuntu extras, would be nice if you could send them as a patch. Are you using some other version than 4.19 or 5.4-rcX?
@Hauke, this was intended for backport-iwlwifi[1], so I re-filed as bug 205839 under wireless component. [1]: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/
