Hello,

Do you have more informations about this message?
I have this sometimes but don't know what is it.
Do you need more informations to help me?

Best regards.

A kernel warning is usually not a symptom of bugs, but sometimes it may be. Of course, it needs to be analyzed.

1. Could you attach the entire output of dmesg here? If brcmsmac driver had output some diagnostic messages before that warning, they could be helpful.

2. Is it 32-bit or 64-bit system?

3. Any information about what was done when this warning triggered could be valuable here. Did you download files or just browsed the web, or did something else? Or, perhaps this occurs only when the wireless connection is just being started, etc.? Feel free to post here whatever else you think could be relevant.
