+ ===== Original Bug Description =====
+
Intel Wireless-AC 9462/9560 on CML was previously enabled via bug
1833065, bug 1834415 and bug 1834464. However on ICL, it fails to
startup with following error messages with kernel v5.2-rc7:
- iwlwifi 0000:00:14.3: loaded firmware version 48.13675109.0 op_mode iwlmvm

Also tried backport-iwlwifi out-of-tree driver revision 7858 (HEAD at
the moment) with no luck.
