“SWBA overrun” in dmesg

Software SW bugs discussion

I’m seeing a lot of this in dmesg:

[31358.952166] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 1, skipped old beacon
[31358.959672] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped old beacon
[31358.967254] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 1, skipped old beacon
[31358.974764] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped old beacon
[31358.982261] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 1, skipped old beacon
[31358.991854] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped old beacon
[31358.999372] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped old beacon
[31532.481817] ath10k_pci 0000:02:00.0: SWBA overrun on vdev 1, skipped old beacon
[31532.489716] ath10k_pci 0000:02:00.0: SWBA overrun on vdev 0, skipped old beacon
[31532.497844] ath10k_pci 0000:02:00.0: SWBA overrun on vdev 1, skipped old beacon
[31532.505421] ath10k_pci 0000:02:00.0: SWBA overrun on vdev 0, skipped old beacon
[31532.512933] ath10k_pci 0000:02:00.0: SWBA overrun on vdev 1, skipped old beacon

This happens with both the included WLE900VX (02:00) and a WLE1216v5 (03:00).

It seems to work despite this, but I can’t really tell if there’s a real problem since clients just switch to a different AP if they have an issue.
