Hi all.
I’ve been experimenting with a generic QCA6174 hw 3.0 card that was purchased
with my Protectli Vault appliance (https://protectli.com/product/m2-wifi/)
which looks to just be this device resold:
https://www.jetone.com.tw/jww6051.html
The device per lspci looks like so:
07:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network
Adapter (rev 30)
Subsystem: Qualcomm Atheros Device 3361
Flags: bus master, fast devsel, latency 0, IRQ 176
Memory at b1000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [40] Power Management version 3
Capabilities: [50] MSI: Enable+ Count=1/8 Maskable+ 64bit-
Capabilities: [70] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [148] Virtual Channel
Capabilities: [168] Device Serial Number 00-00-00-00-00-00-00-00
Capabilities: [178] Latency Tolerance Reporting
Capabilities: [180] L1 PM Substates
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
This is an arch linux kernel: 6.2.8-arch1-1#1 SMP PREEMPTY_DYNAMIC, and
everything is the latest generally available as per the date of this original
email, March 28, 2023.
The default linux firmware that ships with arch (which uses the latest per
hashes of the latest available on github) crashes as i’ll describe below...
If I use firmware version
QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00132-QCARMSWP-1, everything
works perfectly. If i use any firmware newer than version 00132, i get the
following crash during in module load:
(these are the only dmesg lines emitted, and the adapter interface does not
plumb)
[timestamp] ath10k_pci 0000:07:00.0: wmi unified ready event not received
[timestamp] ath10k_pci 0000:07:00.0: device has crashed during init
[timestamp] ath10k_pci 0000:07:00.0: device has crashed during init
[timestamp] ath10k_pci 0000:07:00.0: failed to wait for target init: -70
[timestamp] ath10k_pci 0000:07:00.0: could not init core (-110)
[timestamp] ath10k_pci 0000:07:00.0: could not probe fw (-110)
Does anyone have ANY ideas why this particular card is crashing on the most
recent firmwares? I am glad to experiment to try and figure this out with
others’ help.
Cheers
