[SOLVED] kernel: iwlwifi

i have a 6.7.8-arch1-1 kernel and Network controller: Intel Corporation Wi-Fi 6 AX201 (rev 20) wifi net controller. Sometimes when viewing high quality videos or playing games the video and audio mekes "a hop" its like the pc gets freezed some time. Inclusive some time back i got the PC totally freezed. after some reserch i found the next topic: https://bbs.archlinux.org/viewtopic.php?id=254766 and put the suggested parameters to iwlwifi:

    options iwlwifi 11n_disable=1
    options iwlwifi swcrypto=0
    options iwlwifi bt_coex_active=0
    options iwlwifi power_save=0
    options iwlwifi uapsd_disable=1
    options iwlmvm power_scheme=1

and got no more crashes but still having the hops. Yesterday i checked for log errors immediately after one hops and found the same errors as before when a chash happened:

kernel: iwlwifi 0000:00:14.3: Microcode SW error detected. Restarting 0x0.
kernel: iwlwifi 0000:00:14.3: Start IWL Error Log Dump:

sorry for my english, not a native

Re: [SOLVED] kernel: iwlwifi

The firmware crashed, might have restarted.
Please use [code][/code] tags, not random markup.
Also please don't copypaste out of the pager, it truncates the output.

Please post your complete system journal for a boot covering such incident, eg: 

sudo journalctl -b | curl -F 'file=@-' 0x0.st

for the current one.

It crashes, like, a lot… but there's no pattern to it (most of the journal is just snapd noise)

Try "pcie_aspm=off"

systool -vm iwlwifi

suggests that the parameters were actually applied?
(You're certainly connecting to a 5GHz AP)

Re: [SOLVED] kernel: iwlwifi

i dont think so... this was the output:

Module = "iwlwifi"

  Attributes:
    coresize            = "573440"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "1"
    srcversion          = "75ACCACC9BA61D0A56C8DF5"
    taint               = ""
    uevent              = <store method only>

  Parameters:
    11n_disable         = "1"
    amsdu_size          = "0"
    bt_coex_active      = "N"
    debug               = "0"
    disable_11ac        = "N"
    disable_11ax        = "N"
    disable_11be        = "N"
    enable_ini          = "16"
    fw_restart          = "Y"
    led_mode            = "0"
    nvm_file            = "(null)"
    power_level         = "0"
    power_save          = "N"
    remove_when_gone    = "N"
    swcrypto            = "0"
    uapsd_disable       = "1"

  Sections:

and my /etc/modprobe.d/iwl.conf is this:

options iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
  iwlmvm power_scheme=1 
  iwlwifi d0i3_disable=1 
  iwlwifi uapsd_disable=1 
  iwlwifi lar_disable=1
  iwlwifi pcie_aspm=off

obviously rebooted after modifying iwl.conf

Re: [SOLVED] kernel: iwlwifi

"pcie_aspm=off" is not an option for iwlwifi, but global https://wiki.archlinux.org/title/Kernel_parameters
It is then

options iwlmvm power_scheme=1

and the other iwlwifi parameters you tried to add go into the first "options iwlwifi" line, trailing the present ones.
"swcrypto=1" makes probably more sense to test.
Also eg. "lar_disable" is no longer a valid option, check "modinfo iwlwifi" for the available ones.

Re: [SOLVED] kernel: iwlwifi

And for future readers, please be more specific about the ultimately mitigating configuration.
