Subject: iwlwifi: 9260: Spurious "Unhandled alg: 0x707" and 0x71b
Date: Fri, 16 Aug 2019 16:55:27 +0800
Message-ID: <> (raw)


I've been getting "Unhandled alg: 0x707" or 0x71b randomly
on my Intel 9260. It seems to happen most often when it
associates to a new AP (or roams to a different one that
has the same SSID/authentication). It also seems to happen
only with particular APs. (I don't have access to the APs,
so there's not much I know about them.)

I applied the two patches mentioned in Bugzilla #203593[1]
i.e. "iwlwifi: mvm: Allow multicast data frames only when
associated" and "iwlwifi: mvm: Allow multicast data frames
only when authorized" on top of iwlwifi in 5.2.8, which
improved the situation a lot, but it still happens pretty


I'll try to collect some debug data soon. Also, I'll try
to see if my 8260 has the same issues.

Is there anything else I should try or any other patches I
should backport?
