Another thing ... I don't know what the hack is going on here, since
-rc6 I think I get *loads* of messages:
delba from 00:0a:79:eb:56:10 (initiator) tid 0 reason code 39
After last reboot in about 10min (920.95) I got 414 of these lines.
Always in a triple:
[ 914.882870] delba from 00:0a:79:eb:56:10 (initiator) tid 0 reason code 39
[ 914.882881] Rx BA session stop requested for 00:0a:79:eb:56:10 tid 0 inititator reason: 0
[ 915.012136] Rx A-MPDU request on tid 0 result 0
[ 916.157983] delba from 00:0a:79:eb:56:10 (initiator) tid 0 reason code 39
...
No idea if that helps in any way, but it is new.
Interestingly, after doing rfkill block wifi; sleep 10; rfkill unblock wifi,
and that sometimes 2 or three times, at some point these messages disappear
and I have only:
[18876.624068] tx session timer expired on tid 0
[18876.624117] Tx BA session stop requested for 00:0a:79:eb:56:10 tid 0
[18876.644224] Stopping Tx BA session for 00:0a:79:eb:56:10 tid 0
[18877.609764] Open BA session requested for 00:0a:79:eb:56:10 tid 0
[18877.640279] activated addBA response timer on tid 0
[18877.642218] switched off addBA timer for tid 0
[18877.642224] Aggregation is on for tid 0
(again many of them)
Best wishes
Norbert
