I find this patch breaks my Asus UX433FA
Intel Corporation Cannon Point-LP CNVi [Wireless-AC] (rev 30)
[ 4.350690] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)
[ 4.352211] iwlwifi 0000:00:14.3: Can find a correct rfid for crf id 0x5a2
[ 4.352239] iwlwifi: probe of 0000:00:14.3 failed with error -22
it worked prior. I notice a few other people online with the same
cannon point asus with the same issue.
I'm not sure what other diagnostics i can provide but more than happy
to. Is there a way to dump the OTP out?
