So, it seems I have the exact same problem in "Qualcomm Atheros QCA9565 / AR9565" since Monday, and my outputs are pretty much the same except I don't get this message: мар 22 19:49:29 fsa-k75de kernel: ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x02000020 DMADBG_7=0x00006100 dmesg output: ``` [qua mar 23 10:05:44 2022] wlp2s0: authenticate with xx:xx:xx:xx:xx:xx [qua mar 23 10:05:44 2022] wlp2s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [qua mar 23 10:05:44 2022] wlp2s0: authenticated [qua mar 23 10:05:44 2022] wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3) [qua mar 23 10:05:44 2022] wlp2s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0xc11 status=0 aid=1) [qua mar 23 10:05:44 2022] wlp2s0: associated [qua mar 23 10:05:44 2022] ath: EEPROM regdomain: 0x804c [qua mar 23 10:05:44 2022] ath: EEPROM indicates we should expect a country code [qua mar 23 10:05:44 2022] ath: doing EEPROM country->regdmn map search [qua mar 23 10:05:44 2022] ath: country maps to regdmn code: 0x3b [qua mar 23 10:05:44 2022] ath: Country alpha2 being used: BR [qua mar 23 10:05:44 2022] ath: Regpair used: 0x3b [qua mar 23 10:05:44 2022] ath: regdomain 0x804c dynamically updated by country element [qua mar 23 10:07:43 2022] i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector DP-1: switching from hotplug detection to polling [qua mar 23 10:12:20 2022] i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector DP-1: switching from hotplug detection to polling ``` To reproduce: enable wireless and begin working.

I have a similar symptom with wifi pausing and ksoftirqd getting a lot of cpu with kernel 5.16.15-101.fc34.x86_64 but not with kernel 5.16.11-100.fc34.x86_64. My laptop is Sony Vaio VPCCB4Q1E. dmesg has "ath9k 0000:02:00.0 wlp2s0: renamed from wlan0" and "usbcore: registered new interface driver ath3k" *** Bug 2068272 has been marked as a duplicate of this bug. *** I had the same issue. Fedora 35 was working fine. On march 22nd wifi began to behave inconsistently immediately after upgrading the linux kernel from 5.16.15 to 5.16.16. I am using a Dell Inspiron 7520 and my wifi adapter is Qualcomm Atheros AR9485. Last night and this morning wifi seems to be working well, so I wonder if this has been fixed? (In reply to Joao Carvalho from comment #5) > Last night and this morning wifi seems to be > working well, so I wonder if this has been fixed? Wifi disconnected a couple of minutes after I posted this, so no, it hasn't been fixed. Problem remains. *** Bug 2068350 has been marked as a duplicate of this bug. *** The same issue with kernels >5.16.14. Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01). After about 1 minute the connection hangs. Pings do not go. The reconnection saves for yet another 1 minute.

If anyone wants to give https://koji.fedoraproject.org/koji/taskinfo?taskID=84697781 a try, and let me know if it works for you. It is not secure boot signed because it is a scratch build, but it contains a patch that upstream is tossing around. There is a still a considerable amount of discussion on it. Would like to add that I'm running Fedora 36 Workstation Pre-release, and this issue is happening with me after the update from Linux 5.17-rc7 to 5.17 as well, this issue is not just limited to 5.16.x series. lspci: 09:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01) dmesg: [12193.613742] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x02000020 DMADBG_7=0x00006100 [12194.669386] wlp9s0: authenticate with xx:xx:xx:xx:xx:xx [12194.669427] wlp9s0: bad VHT capabilities, disabling VHT [12194.669432] wlp9s0: 80 MHz not supported, disabling VHT [12194.687759] wlp9s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [12194.701654] wlp9s0: authenticated [12194.701806] wlp9s0: associating with AP with corrupt probe response [12194.702140] wlp9s0: associate with xx:xx:xx:xx:xx:xx (try 1/3) [12194.708789] wlp9s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x411 status=0 aid=1) [12194.708917] wlp9s0: associated [12194.709086] ath: EEPROM regdomain: 0x8164 [12194.709090] ath: EEPROM indicates we should expect a country code [12194.709091] ath: doing EEPROM country->regdmn map search [12194.709093] ath: country maps to regdmn code: 0x5b [12194.709094] ath: Country alpha2 being used: IN [12194.709096] ath: Regpair used: 0x5b [12194.709098] ath: regdomain 0x8164 dynamically updated by country element Essentially identical to the above reports. Yes, that would make since given that upstream has not accepted a fix yet. (In reply to Justin M.

Forbes from comment #9) This fixes my, Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter - many thanks. Before this patch, when streaming videos, my Acer Aspire E1-570 laptop's log repeatedly contained the message wpa_supplicant[959]: wlp3s0: CTRL-EVENT-BEACON-LOSS when using any of the 3 following kernel versions 5.16.15-201.fc35.x86_64 5.16.16-200.fc35.x86_64 5.16.17-200.fc35.x86_64 The patch in the 5.16.17-201.fc35.x86_64 kernel, fixes the above ath9k driver issue for my laptop. Now I don't have to revert back to kernel version 5.16.14-200.fc35.x86_64, to get perfect Wi-Fi access.
