FS#2480 - Mainline ath10k causes crahes in ipq806x / R7800

The mainline ath10k mainly works in R7800, although it has some problems the show up in the logs as

"ath10k_pci 0001:01:00.0: SWBA overrun on vdev 0, skipped old beacon"

.

That seems to increase CPU utilisation somewhat, but the router still works.

Every now and then the router also crashes. I have attached a serial logger to the router, so I managed to capture the following crash series. 4-5 crashes during a few hours when the router was mainly idle.

24.05.2020 : A task closure has been requested. Reason for request: Likely fixed with 289c632425 (bumping the mac80211 version to kernel 5.7-rc3).
timkgh commented on 16.02.2020 17:53

It would be good to still support the classic "old" ath10k driver and firmware in master for as long as possible as "ct" is buggy with various clients to the point where it's not feasible to use. IMHO we rushed to make "ct" the default.

Hannu Nyman commented on 22.05.2020 09:29

Possibly fixed with 289c632425 (bumping the mac80211 version to kernel 5.7-rc3).
