Check youor mesages and look for EDC asset. There is a fix teed up which
may help your case.

 I have seen this "EDC assert" issue with 8265 [1] and the fix is given
in comment #42.  I have tested it on kernel 5.2-rc7 and works fine.
This impacts all pre-9000 intel wifi cards.

This will NOT make it into 5.2, as Emmanual G points out, as its late in
the cycle; presumably will be in 5.2.1 and 5.3.

A work around you might try is to add this iwlwifi option - then reboot.

# cat >> /etc/modprobe.d/iwlwifi.conf
options iwlwifi swcrypto=1
