[Bug 1517882] Re: Excessive logging and problems with brcmsmac: bcma0:1: START: tid 1 is not agg'able

  Thread Previous • Date Previous • • Thread Next 
alphac, to clarify the Bug Description:
+ Are the disconnections intentional (you clicked to disconnect)?
+ Is the reconnection problem limited to one access point?
+ What is the access point manufacturer, model, and firmware version?
+ What wireless version are you using (G, N, etc.)?

** Tags added: kernel-bug-exists-upstream-4.3

** Summary changed:

- Excessive logging and problems with brcmsmac: bcma0:1: START: tid 1 is not agg'able 
+ 14e4:4727 unable to reconnect to AP after disconnection

** Description changed:

- Hello I have lots of logs with this message, like 15mb a day. Also the
- module randomly loses ability to connect an AP after a disconnection,
- the only resolution is a reboot, more than one if necessary. The latter
- happens also with the proprietary Broadcom driver.
- 
- brcmsmac bcma0:1: START: tid 1 is not agg'able
+ The module randomly loses ability to connect to an AP after a
+ disconnection, the only resolution is a reboot, more than one if
+ necessary.
