I am using a Thinkpad E490 with the Intel 9260 wireless card, Kubuntu 19.10 and kernel 5.3.0-29-generic.
05:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29) I have tried several iwlwifi module options (11n_disable=1, 11n_disable=8, power_save=0, bt_coex_active=0, lar_disable=1, swcrypto=0), older firmwares, as well as the dkms backport module. I have tested nearly all variations and the error did not disappear. This is what I can summarize: The error occurs after booting Windows (Fast Boot is disabled - which has no positive effect) and then booting Linux afterwards. The error is quickly reproducible using speedtest.net (thanks @Hairong Zhu (hrzhu)) or transferring a larger file of any kind. The ONLY solution to the problem in my case is: Shutting the system down and removing the power adapter. Then boot Linux and the error is gone (no module options, current firmware iwlwifi-9260-th-b0-jf-b0-46.ucode, kernel 5.3.0-29-generic). Never boot from Windows to Linux without powering down completely, then you should be fine until a fix is available. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848921 Title: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848921/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
