[Fix] Resolved in upstream commit 318c64abfb33 ("iwlwifi: update gl FW for core80-165 release"). While the iwlwifi firmware updates come with a sequential manner, it pulls a few more: * 765492b8b ("iwlwifi: add new FWs from core81-65 release"), already in Mantic * a07fd0b96 ("iwlwifi: add new FWs from core83-55 release") * f27dec616 ("iwlwifi: fix for the new FWs from core83-55 release") These contain firmware blob for ucore 84/86, and are not used by kernels < v6.7. [Test Case] Use checkbox reboot stress test case to observe iwlwifi dmesg logs: $ checkbox-cli run com.canonical.certification::stress/reboot [Where problems could occur] Opaque firmware update. No known issue found yet after the update. [Other Info] This affects series with kernels that load iwlwifi ucode 83 firmware, namely Noble, Mantic, and for oem-6.5, Jammy. ========== original bug report ========== Within stress reboot tests, iwlwifi may fail to load firmware and triggers retry, and finally makes wifi operative.
