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 ------------------------------------------------------------------------ Norbert Preining preining@{jaist.ac.jp, logic.at, debian.org} JAIST, Japan TeX Live & Debian Developer DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------ MELCOMBE REGIS (n.)
