Comment 8 for bug 1858366

Yes, It is
ll /lib/firmware/ | grep iwl
-rw-r--r-- 1 root root 2677620 Jan 5 23:24 iwlwifi-9000-pu-b0-jf-b0-34.ucode

Apparently after 3/4 days it's working again, I've just updated one package (libc) from apt-get update since then and now it works.. now my dmesg log looks like

 dmesg |grep iwl

This is kind of weird...

I noticed weeks ago, that from time to time it started to fail, probably due to the heat?
