Wifi not working with kernel 5.7.2

Hello, I just upgraded to kernel 5.7.2 and wifi suddenly stopped to work (not even detected with lspci, rfkill or any command I tried). Anyway I "solved" it downgrading to 5.6.15.

I'm using a Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)

Any idea of what could be happening?

Regards.

EDIT: I also tried modprobing iwlwifi (which I think it was loaded so no luck)

sudo journalctl -b

Ok, journalctl -b | grep wireless with kernel 5.7.2 returns:

 jun 11 20:41:12 archMsiR0Cif kernel: WARNING: CPU: 0 PID: 512 at drivers/net/wireless/intel/iwlwifi/pcie/drv.c:1114 iwl_pci_probe+0x4a0/0x5c0 [iwlwifi] 

With 5.6.15 I don't see that message:

 jun 11 20:45:44 archMsiR0Cif NetworkManager[953]: <info>  [1591901144.1880] device (wlo1): Activation: (wifi) Stage 2 of 5 (Device Configure) successful. Connected to wireless network "

@thongil: did you actually READ that linked post? Go back and read the part about large files.

Re: Wifi not working with kernel 5.7.2

Does look like a regression in 5.7.  Please report it upstream https://wireless.wiki.kernel.org/en/use … /debugging
You could also bisect between 5.6 and 5.7 to try and determine the cause.
Could be the same issue as https://bugs.archlinux.org/task/66977

Thank you all for your help and patience. I'll try to submit a bug, in the meantime I'll use 5.6.15.
