Seth, I think the patch above is safe for 3.13. I don't know how to upstream that since it is fixed in 3.15 and this basically means that I need a patch in 3.13 / 3.14 which won't be in Linus's tree ever... But that's just a dev process issue. From a technical POV, this patch should go in 3.13.
It explains why -7.ucode works I haven't checked, but I guess that -7.ucode doesn't support the feature I disable in my patch. This code (power code) has been heavily reworked in 3.15 and other users reported that the issue doesn't reproduce on 3.15 even with 22.24.8.0 firmware. So, I'd say that I think I'd like to have the -9.ucode patch and the patch from comment $47. As for your comment #45 (why launchpad doesn't have a reply button :)) - yes you are right. You only need to change the define. I hope we'll be able to get some testing... I really want to solve / close / forget this issue :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1293569 Title: iwlwifi-7260-8.ucode causes network disconnections problems Status in “linux-firmware” package in Ubuntu: Confirmed Status in “linux-firmware” source package in Precise: Fix Released Status in “linux-firmware” source package in Trusty: Fix Released Bug description: Running 14.04 (beta) with Kernel 3.13.0-17-generic I've encountered a strange and reproducible error with the iwlwifi-7260-8.ucode firmware. This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will connect fine to wifi for 30 or 40 mins at a time, then will start dropping connections repeatedly. Even modprobe -r unloading and reloading doesn't fix the issue, only a reboot will temporarily solve it for 40 mins at a time. Moreover, here is what's strange, is during these episodes of disconnection it seems to affect the actual router (2Wire), as the other devices in the house will also start to have issues (very slow connections, limited range,etc). Once I reboot this laptop everything and all devices will return to normal. This issue has been fixed by me manually removing the -8 firware from /lib/firmware and letting the -7 firmware load instead. Since that has been done there has not been a single issue of this happening (now going on 4 days). let me know if there is any other information you would like me to provide.
