[BUG] Driver loads firmware but times out on activation (Acer Aspire 3 A315-59)

[Kay340D]

Hello, and thank you for your incredible work on this driver. I have been testing it and have found a reproducible bug that I hope this report can help solve.

System Information:

Laptop Model: Acer Aspire 3 A315-59-78NS

WiFi Card: MEDIATEK Corp. Device 7902 (PCI ID 14c3:7902)

Operating System: Arch Linux

Kernel Version: 6.16.4-arch1-1

Steps to Reproduce:

Cloned the repository.

Successfully compiled the driver from the linux-6.16/drivers/net/wireless/mediatek/mt76 directory.

Copied both required firmware files (WIFI_MT7902_patch_mcu_1_1_hdr.bin and WIFI_RAM_CODE_MT7902_1.bin) from the Wireless LAN_MTK... folder to /lib/firmware/mediatek/.

Loaded the kernel modules in order (mt76.ko, mt76-connac-lib.ko, mt792x-lib.ko, and mt7902/mt7902e.ko) using sudo insmod.

The system successfully creates a wireless interface (e.g., wlan1).

Attempted to activate the interface with sudo ip link set wlan1 up.

Expected Result:
The wlan1 interface should be activated and change its state to UP.

Actual Result:
The command sudo ip link set wlan1 up hangs for several seconds and then fails with the error: RTNETLINK answers: Connection timed out. The driver appears to crash at this stage.

Relevant dmesg Log:
The log clearly shows that both firmware files are loaded successfully, but the driver then fails with communication timeouts.

[56746.580586] mt7902e 0000:2a:00.0: Message 00020001 (seq 9) timeout

Additional Steps Taken:
I also tested loading the mt7902e.ko module with the disable_aspm=1 parameter. The result was exactly the same, with the same timeout errors.

Thank you again for all your effort on this project. Please let me know if you need any more information or logs from my system.

The driver is incomplete now, I tried many things. My kernel crashed many times when I tested this driver experiment. Now I have some issues so that I can not give more time to it. Driver is now able to detect wifi present near you, now it's time to implement beacon frame in the driver and change some tlv to add bss. I tried but unsuccessful. You can paste your dmesg output to comment, I will check when I have free time. If you don't want time in dmesg type 'dmesg -t'
