I don't commit to wireless-dev, John does. I'd love if the patches were in already ;) And I think he even said he had committed them but they didn't show up so something must have gone wrong (forgot to push out to kernel.org maybe) johannes signature.asc Description: This is a digitally signed message part

Patches are on the linux-wireless mailing list. Johannes, would it be possible to commit patches faster, please? Now that I told Michael about git-update-server-info, his changes are downloadable as soon as he makes a commit. wireless-dev.git, on the other hand, is a mess and has been for some time (since Friday, I believe). It is a problem for projects like DadWifi that recommend to use the top of wireless-dev.git. Yes, I know, breakage is unavoidable to a certain degree, but it shouldn't come to the situation when the patches are known, nobody objects, yet the repository stays broken and all newcomers have to be told about the problem. That's not to offend you or anyone. It's just something that would help a lot. -- Regards, Pavel Roskin - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

The current Broadcom driver can be loaded from http://bu3sch.de/git/wireless-dev.git (please load it on top of wireless-dev.git to save bandwidth) It doesn't include the latest breakage from wireless-dev, but it does include some important fixes. Although I haven't seen a problem like yours, I strongly suggest that you try the above repository and post your results to the bcm43xx-dev list. Even if the results are more positive :) -- Regards, Pavel Roskin - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
