Bug Description
[SRU Justification]
[Impact]
iwlwifi may encounter firmware crash when running 5.13 kernel with
outdated firmware.
[Fix]
Commit 2b13afc1a0ff82 ("iwlwifi: add new FWs from core60-51 release")
added new rev -63 firmware.
[Test Case]
1. disconnect/connect stress
$ sudo add-apt-repository ppa:checkbox-
$ sudo apt install plainbox-
$ checkbox-cli run com.canonical.
ignore connect bluetooth part, and set the SSID and password to proceed.
2. suspend/resume stress
$ for i in $(seq 200); do \
echo "Round $i..."; \
nmcli d; \
sleep 15; \
rtcwake -m mem -s 15; \
done
[Where problems could occur]
Rev -63 firmware is only used by 5.13 kernel or newer.
[Other Info]
While 5.13 kernel is only available in Focal and Impish, only Focal is
nominated here.
