Hi All Brandon Dell was kind enough to do some testing using the compat-wimax tree, and here is what he found: 2.6.29: SUCCESS 2.6.29 + compat-wimax (as of 11/30) FAIL 2.6.31 FAIL 2.6.31 + compat-wimax (as of 11/30) FAIL Which truly means that something we do in the driver is causing the issue. On the bright side, bisecting the compat-wimax tree is way easier, so I am hoping we can get more information from that. OTOH, I am going to be mostly offline for a few days, but I'll try to keep an eye on how things are going. Thank you Brandon!
