Disabling "iwlwifi 0000:00:14.3: Unhandled alg: 0x707" from flooding the logs
I have a certain problem with my wifi card, which makes the following message :
iwlwifi 0000:00:14.3: Unhandled alg: 0x707be outputted a dozen of times per second to the syslog and kern.log files in /var/logs whenever connected.
The problem with the wifi card itself is a long-running one that I tried and failed many times to solve, but weirdly enough the wifi still works correctly, so I'm not asking specifically to tackle it down.
The problem is said log files grow of around 4 MB per minutes for a hefty 5 GB per day.
The /var directory is its own partition, so that limits problems, but I still need to force a logrotate and delete archived files any time I want to run an apt upgrade, for example, reading the log files for any reason is impossible, as well as using the ttys because that message is also outputted on them.
Would there be a way to disable the outputting of that message to the logs?
Config :
- Ubuntu 18.04
- Kernel 5.0.0-36-generic
- Wifi card : Intel Corporation Wireless-AC 9560

I was trying to solve this problem too and I think I did it. I turned off some encryption option in iwlwifi and I'm not seeing the constant stream of "Unhandled alg" errors in my log files anymore.
I added this line:
options iwlwifi swcrypto=0To this file:
/etc/modprobe.d/iwlwifi.confand rebooted.
If you need whatever "swcrypto" does, I guess this isn't the best option. But maybe this helps others figure out the problem?
