Hi Bjoern - I just tested this out on my laptop and it looks like I'm 
seeing some improvement in loading firmware on my end, but I am still 
hitting some issues preventing my device from coming up fully.  I think 
this is the pertinent bit from dmesg:

iwlwifi0: loaded firmware version 46.4e1ceb39.0 
9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm
iwlwifi0: Detected Intel(R) Wireless-AC 9560 160MHz, REV=0x312
iwlwifi0: base HW address: d8:3b:bf:82:d4:4e, OTP minor version: 0x0
iwlwifi0: lkpi_sta_scan_to_auth: waiting for 5 queues to be allocated by 
iwlwifi0: No beacon heard and the time event is over already...
iwlwifi0: Couldn't drain frames for staid 0, status 0x8
iwlwifi0: lkpi_iv_newstate: error -5 during state transition 5 (RUN) -> 
0 (INIT)
WARNING mvm_sta->dup_data == ((void *)0) failed at 
iwlwifi0: Microcode SW error detected. Restarting 0x0.

I've attached the iwlwifi0 lines from my system to this email in case 
its helpful for you.  happy to test out any other patches or gather more 
info :^)

oh here's the device info:
iwm0@pci0:0:20:3:       class=0x028000 rev=0x30 hdr=0x00 vendor=0x8086 
device=0x9df0 subvendor=0x8086 subdevice=0x0030
     vendor     = 'Intel Corporation'
     device     = 'Cannon Point-LP CNVi [Wireless-AC]'
     class      = network
