Details

Description:
After couple of hours with wifi connection, wifi disconnects, wifi fails to scan, iwlwifi tries to restart, iwlwifi firmware crashes.
After restarting the machine, wifi connection can be established again.
Turning wifi on and off or suspending the machine sometimes triggers the crash but not always.
Logs before 5.5.6 were little different, I can add them if necessary

Additional info:
* linux 5.5.6-arch1-1
* linux-firmware-20200204.b791e15-1
* Intel(R) Dual Band Wireless AC 9560, REV=0x318
* ASUSTeK COMPUTER INC. ZenBook UX433FN_UX433FN/UX433FN, BIOS UX433FN.309 10/14/2019


Steps to reproduce:
Connect to wifi.
After some time iwlwifi crashes

Errors start here, full logs in attachment.

Restarting networking seems to resolve the issue. Curiously, journalctl shows the card as a 9560:
Feb 27 17:51:17 carbon kernel: iwlwifi 0000:00:14.3: Detected Intel(R) Wireless-AC 9560 160MHz, REV=0x354

But lspci shows it as a 9462:
00:14.3 Network controller: Intel Corporation Wireless-AC 9462
