MT7902: hardware init failed ("Timeout for driver own", ASIC revision: 30003, Manjaro 6.15)

Hello!

I'm trying to get Wi-Fi working on my laptop with a MediaTek MT7902 chip under Manjaro Linux (kernel 6.15.7-1-MANJARO).
The driver builds and the module loads, but no Wi-Fi interface appears, and I see repeated errors in dmesg:

mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

System information:

• Distribution: Manjaro Linux
• Kernel version: 6.15.7-1-MANJARO
• Chip: MediaTek MT7902
  (lspci: 02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902])
• ASIC revision: 30003 (from dmesg)
• Driver: OnlineLearningTutorials/mt7902_temp (latest commit, cloned with --depth 1)
• Firmware files are present in /lib/firmware/mediatek/:
  • WIFI_MT7902_patch_mcu_1_1_hdr.bin
  • WIFI_RAM_CODE_MT7902_1.bin

What I have tried:

• The module builds and loads without errors.
• Firmware files are unpacked and permissions are set.
• Tried different firmware versions (from Windows driver and linux-firmware).
• Tried different kernel versions (6.12, 6.15).
• Secure Boot is disabled.
• The chip is visible in lspci, but no Wi-Fi interface appears.
• No "firmware not found" errors in dmesg, only "Timeout for driver own" and "hardware init failed".

dmesg output:

mt7902e 0000:02:00.0: enabling device (0000 -> 0002)
mt7902e 0000:02:00.0: disabling ASPM  L1
mt7902e 0000:02:00.0: ASIC revision: 30003
mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

Questions:

• Is ASIC revision 30003 supported by this driver?
• Is there a working driver/firmware combination for MT7902 on Linux?
• Is there anything I can do to get Wi-Fi working on this chip?

Thank you for your work! I am ready to provide any additional logs or information if needed.

Start by reproducing the failure with the MT7902 device, Manjaro kernel 6.15.7-1-MANJARO, and the mt7902_temp module, then inspect the dmesg sequence around ASIC revision 30003 and the driver-own timeout. Compare the available firmware files in /lib/firmware/mediatek/ with the driver's supported revisions. Done means identifying a supported driver/firmware combination or documenting that this ASIC revision cannot initialize.
