Bug Description

A Gigabyte GC-WBAX210 WIFI 6E Aorus PCI card worked fine under Ubuntu 22.04 LTS but under Ubuntu 22.10 fails to initialize properly half of the time. When this occurs, the kern.log shows...

Looking through the various bug reports against iwlwifi in bugzilla related to iwlwifi driver initialization failures and previous workarounds, I added...

options iwlwifi power_save=0
options iwlmvm power_scheme=1
options iwlwifi uapsd_disable=1

to /etc/modprobe.d/iwlwifi.conf. Tentatively, this seems to have suppressed the "CSR_RESET = 0x10" failures in this driver. I would note that the occurance of these failures was reduced under the 5.19.0-21.21 kernel package but not entirely eliminated.

Apparently the options workaround doesn't completely eliminate the bug. It still occurs around five percent of the time when booting kinetic.

Unfortunately, this bug has gotten worse under 5.19.0-23.24 despite the options hack. On a cold boot, about half the time the iwlwifi driver shows the bug.

It appears that this is fixable with a BIOS update on the Gigabyte X570 UD v1.1 motherboard. Upgrading from the F32 stable BIOS release to the F34 stable BIOS release captures the following change from the F33g beta BIOS release...

3. Fix USB 2.0 devices stability and compatibility

which makes sense as the Gigabyte GC-WBAX210 WIFI 6E Aorus PCI card is connected to a motherboard USB 2.0 connector. Since updating to F34, the boot issues with iwlwifi have disappeared. It would still be nice for upstream to make the iwlwifi drivers as robust to BIOS defects as the Windows drivers which always worked fine under F32.

Upgrading the BIOS to capture the USB 2.0 fixes significantly reduced the occurance of this bug but unfortunately doesn't totally eliminate it. I should note that the Ubuntu 22.04 LTS kernels initially suffered from this bug to a small degree but that by 22.04.1 LTS, the issue was extremely rare. It is unfortunate how fragile iwlwifi is.

After many false starts, the following similar RedHat bug report, gave me a hint to a workaround that suppresses the CSR_RESET errors in iwlwifi.

https://bugzilla.redhat.com/show_bug.cgi?id=2138790

Bug 2138790 - No WiFi on T16 Intel Gen 12th Alder Lake Wifi 6E AX 211 [NEEDINFO]

This bug report cites the following kernel commit as being the source of the bug.

https://github.com/torvalds/linux/blob/4fe89d07dcc2804c8b562f6c7896a45643d34b2f/drivers/net/wireless/intel/iwlwifi/iwl-io.c#L478-L483

Noticing this section in that file...

/*
  * Wait for clock stabilization; once stabilized, access to
  * device-internal resources is supported, e.g. iwl_write_prph()
  * and accesses to uCode SRAM.
  */

err = iwl_poll_bit(trans, CSR_GP_CNTRL, poll_ready, poll_ready, 25000);
if (err < 0) {
IWL_DEBUG_INFO(trans, "Failed to wake NIC\n");

iwl_dump_host_monitor(trans);
}

... I decided to disable the BIOS setting for "Wake On LAN" in the Power section of the Gigabyte X570 UD v1.1 F37d BIOS (which is on by default).

So far this change has fully suppressed the CSR_RESET bug. Disabling "Wake On LAN" in BIOS is sufficient without resorting to...

options iwlwifi power_save=0
options iwlmvm power_scheme=1
options iwlwifi uapsd_disable=1

in /etc/modprobe.d/iwlwifi.conf.
