Package: linux-image-5.10.0-9-amd64
Severity: normal

Dear Maintainer,

with the upgrade from kernel version 5.10.0-8-amd64 to version 0-9-amd64 I notice a very annoying issue with my wireless card.

Problem is, the LED is permanently blinking, not (as it was with the former kernel) when there is real trffic.

The kernel module which is responsible for that, is ath5k.ko (This is an Atheros card)
Normally the wireless LED only blinks, when there is real traffic aimed to my IP. 
However, with 0-9- the LED is permanently blinking. 

I could verify, that it is no traffic created by the notebook itself (used 
tcpdump) and killed all network processes (daemons/apps whatever) running on 
the system.

But even when there were no processes running except the one needed for the 
connection with the router, the LED kept on blinking.

Further investigation showed, that the blinking appeared due to the broadcast 
packages sent by the router. The wireless card thinks, this is normal traffic 
and the LED blinks.

This is bad for me, as the LED was in the past often a good sign, when 
soemthing fishy is going on. If the LED is only blinking from time to time, 
everything is ok, but when it was blinking som,ething special is going on 
(i.e. an update is running or freshclam is updating, but also some brute force 
attacks could also be discovered.) 

It would be nice, if you could examine, what has changed at the new kernel, and I would be happy, when I 
could get the old behaviour back.

At the moment I reverted back to kernel 5.10.0-8-0*, which is running perfectly.

Thank you very much for all the help!

Best regards

Hans

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
