This is happening pretty early, did you compile the iwlwifi driver into the kernel (instead of compiling them as modules)? There have been problems when it's in-kernel, so we recommend that you compile them as modules (unless strictly necessary). > I've attached the dmesg in it's entirety. > Booting back to 4.6: > > [ 17.987698] iwlwifi 0000:04:00.0: loaded firmware version > 16.242414.0 op_mode iwlmvm > [ 18.269667] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band > Wireless AC 7260, REV=0x144 This shows that you have iwlwifi-7260-16.ucode in your file system. But here we are reading it much later. So it's possible that the kernel cannot access the firmware at a very early stage (because the filesystem that contains it is not mounted yet) when you use in-kernel. So, first of all, please make sure they're built as modules. We can continue from there then. -- Cheers, Luca. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
