Hello. I have been having problems with my wifi for the past few says.
First it was with an ath9k_htc wifi stick and then I decided to test an intel wifi card.
The card would disconnect randomly with it trying to authenticate but failing for some reason. I am starting to think it is a ploblem with possibly my kernel config or the kernel parameters.
Here is the dmesg output:
https://bin.snopyta.org/?0207dad1b35...xH8NRLccy2q3pB
You can see that there seems to be a ploblem with loading iwlwifi. This happens about an hour or two once I leave my computer alone. It is very strange.
Specifically the stack trace that appears:

Here are my kernel parameter in lilo:
Code:
append = "vt.default_utf8=1 resume=/dev/cryptvg/swap slab_nomerge slub_debug=FZ init_on_alloc=1 init_on_free=1 page_alloc.shuffle=1 pti=on vsyscall=none debugfs=off module.sig_enforce=1 spectre_v2=on spec_store_bypass_disable=on tsx=off tsx_async_abort=full,nosmt mds=full,nosmt l1tf=full,force nosmt=force kvm.nx_huge_pages=force ipv6.disable=1
random.trust_cpu=off efi=disable_early_pci_dma intel_iommu=on"
Mainly security mitigations and some stuff for encryption (where resume is for example). Also disabling ipv6 since I heard that could fix it. It didn't but I kept it anyway since my network does not even support ipv6.
Here is my kernel config. I do not think it could be a ploblem in the config since I have been using this for a month but the problem appeared about a week ago.
https://bin.snopyta.org/?c6f1e864f1c...PEtVHNuiKjptAM
I have only enabled drivers I need and some security options. I do not have any extra patches on top of the kernel and I am currently using a standard kernel (non libre) since intel wifi won't work on a libre kernel.
The stack traces seem to show some issue with loading the firmware. This happend before the recent update of linux-firmware as well.
I am using coreboot with seabios if that makes a difference.
I do not really know what is happening. I found this fix on iwlwifi fixes git repo which my point to some solution as it does mention beacons:
https://git.kernel.org/pub/scm/linux...mit/?h=pending
Honestly I have no idea what is happening. This happend on usb with a TL-WN422G and with a intel card. May be a problem with my network config? I do not know. I have tried:
- disabling power save
- disabling wireless ac and wireless n
- disabling bt coexist
- using dhcp rather than dhcpd
- disabling iommu
I am very lost. I thought this was specific to th9k_htc but no. Seems to me I configured something wrong in my kernel config. Possibly a security option? I do not know.
Hopefully I find a solution.
EDIT: Switching to 4.19 fixes the issue.
