Perhaps it's a race condition in my userspace where something NetworkManager related is trying to up the interface, I don't know. More below. Regardless, I'm going to have to put off doing more debugging until tomorrow. I've rebooted back into 2.6.23.0 as wireshark doesn't show any packets using 2.6.24-rc3 (the version I've been testing), reported elsewhere, and that's preventing me from doing actual work with my system, as I'm in the middle of trying to enhance a network server for a client. Note, the wireshark issue is very much not a bcm43xx/b43 issue; I'm not trying to lay that at your feet. > So could you please try to reproduce the breakage by reverting that > patch again? Just to make really sure it is this patch fixing the issue > and not just some coincidence. I don't have the patch applied, so that's at least part of the misunderstanding here. All I have is my sequence of "load b43, ssb, nothing happens, unload them, load rfkill, rfkill-input, ssb, b43 and something happens." I could very well be wrong. But I'm at the limit of what I care to know about the b43 driver, and this is where I'm asking for your help. Hopefully tomorrow, I'll be able to build current tip and try this all again, and I'll also try to do it with NetworkManager killed in the background in case it was trying to bring the interfaces up behind my back. > Thanks for your help.
