After updating the kernel to version 5.5 I am getting wifi issues. iwlwifi shows eroor and there is no adapter found
For me the same on 5.6
The right place to submit bugs for kernel drivers is listed in the MAINTAINERS file in the kernel:
You need to prepare at least sudo dmesg output as well as the exact kernels that it worked, and the one that it broke, If they’re both ClearLinux kernels, please try to be as exact as you can (we’ll try our best to poke the maintainers if they are folks from Intel). If they’re not ClearLinux kernels, you should file the bugreport yourself with the listed maintainers.
That goes for both @shans10 and @archimwessling - neither of you gave enough information to troubleshoot the issue since we can’t actually identify the kernel that you are using - 5.5 is not detailed enough.
We also need to know the exact lspci -nn output.
Sorry for not giving any relevant information!

Can you check sudo dmesg | grep firmware and look to see if the driver attempted to load a newer firmware, failed, and fell back to an older firmware version?

The same behaviour was observed for my wireless card and a few more on other distributions that updated their kernel to version 5.5.0 including arch linux and gentoo and I think there is a patch available for it. As far as I know the issue was fixed on both Arch Linux and Gentoo on latest kernel update.
Here’s the link to the issue - Gentoo Forums :: View topic - iwlwifi Fails On Kernel 5.5.0 [solved]
I just got a reply back from a fellow Intel colleague:
Looks like the kernel is indeed broken - we’re trying to see if we can include this commit and … well hopefully that will fix it.
Thank you , I really appreciate it!!!
kernel version 5.5.4-910 will have the referenced change. Please test it when it becomes available in an update, reboot, and report back!
Ok, I will test it and report back as soon as it becomes available!
Yes, the iwlwifi problem has been fixed in the kernel version 5.5.4-910.native!!!
@shans10 If I had kudos points for your response time - you’d score big time. Thanks a ton - I’ve reported back to folks that maintain the driver.
