Hi,

I updated my kernel to 3.8.13 from 3.7.10-r1. Now, whenever I try to connect to eduroam (an 802.11x WPA Enterprise university wireless network using TTLS and MSCHAPv2), NetworkManager times out on "configuring interface" and asks for a password. Booting the old kernel causes it to work absolutely fine, and I can connect to WPA personal networks at least on the new kernel (I haven't tried other WPA Enterprise networks because I don't know of any).

Anyone got any suggestions, or need any more information?

Does it work in v3.10? Does it fail in v3.8?

I put up with it (either connecting to other networks or running the old kernel) until the latest Gentoo kernel (3.10.7) was unmasked, and now it works fine - so I'm pretty sure it was just a kernel bug in 3.8. Sorry I didn't do any more debugging at the time, but I really didn't have a good opportunity to sit down and do a proper test - I've been pretty busy recently.
