OK. The "modinfo -F" command you gave me returns a list of files: ath10k/QCA9377/hw1.0/board.bin ath10k/QCA9377/hw1.0/firmware-5.bin ath10k/QCA6174/hw3.0/board-2.bin ath10k/QCA6174/hw3.0/board.bin ath10k/QCA6174/hw3.0/firmware-6.bin ath10k/QCA6174/hw3.0/firmware-5.bin ath10k/QCA6174/hw3.0/firmware-4.bin ath10k/QCA6174/hw2.1/board-2.bin ath10k/QCA6174/hw2.1/board.bin ath10k/QCA6174/hw2.1/firmware-5.bin ath10k/QCA6174/hw2.1/firmware-4.bin ath10k/QCA9887/hw1.0/board-2.bin ath10k/QCA9887/hw1.0/board.bin ath10k/QCA9887/hw1.0/firmware-5.bin ath10k/QCA988X/hw2.0/board-2.bin ath10k/QCA988X/hw2.0/board.bin ath10k/QCA988X/hw2.0/firmware-5.bin ath10k/QCA988X/hw2.0/firmware-4.bin ath10k/QCA988X/hw2.0/firmware-3.bin ath10k/QCA988X/hw2.0/firmware-2.bin but not all these files exist in the updated firmware build I downloaded as per Kai-Heng Feng's instructions above. And in the directory you had me check are only *.ko files. So I'm not sure what to replace with what here. Sorry, guys, but the last time I built my own kernel was on Slackware Linux 1.18 in 1994 (if memory serves) and the current structure and organization of the various kernel components is a little beyond me. I'm eager to do whatever you need me to do to provide you with the data you need in order to find out what the problem is, but I'm going to need a little bit of hand-holding here. Sorry to be a pain but I'm not at all sure how to proceed at this point to install the updated kernel and firmware modules you need me to try. Any further advise would be appreciated! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1830350 Title: System freezes repeatedly for several seconds; wifi driver related errors Status in linux package in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: New Bug description: I updated my system about a month ago (Fri 26 April 2019). This was the first update in several weeks and installed fresh versions of a whole truck load of applications including a kernel update. Since this latest bunch of updates the system freezes for a few seconds at regular intervals. Not fatal, but very annoying. Output from "journalctl -f" shows the following errors occurring at the same time as these freezes: May 24 10:31:18 dellfvw wpa_supplicant[1078]: wlp3s0: CTRL-EVENT-SCAN-FAILED ret=-110 May 24 10:31:18 dellfvw kernel: ath10k_pci 0000:03:00.0: failed to receive scan abortion completion: timed out May 24 10:31:18 dellfvw kernel: ath10k_pci 0000:03:00.0: failed to stop scan: -110 May 24 10:31:18 dellfvw kernel: ath10k_pci 0000:03:00.0: failed to start hw scan: -110 Corresponding lines in /var/log/syslog: May 24 10:29:16 dellfvw avahi-daemon[1053]: Registering new address record for fe80::424:c75b:2a2d:52e2 on wlp3s0.*.

The freezes last a few seconds. Keyboard input is preserved at this time and typed input appears after the freeze is resolved. Mouse cursor continues to move during freezes but mouse clicks are only processed after the freeze is resolved, i.e. the result of the mouse click is suspended (e.g. buffered) until the system becomes responsive again. For example, clicking on a window during the freeze will focus that window after the freeze has been resolved. The system is a Dell Inspiron 15 3576.

I reported the bug (maybe in the wrong place) but so far I have received no response. I've lived with this for a month or so hoping that further updates would fix the problem but it still persists. Installing the latest firmware update (14 Mar 2019) has no effect. No other changes were made to either hardware or OS configuration.
