I've been debugging MT7925 issues. A few observations on your problem:

The ASIC revision: 0000 points a real poblem

A zero ASIC revision means the driver cannot read hardware registers over PCIe. The MCU timeouts are a consequence - the hardware isn't responding at all.

Common causes:

1. PCIe link not trained properly - device present but not communicating
2. Power management issues - device in low-power state that driver can't wake
3. BIOS/platform issues - X870 is a brand new platform

Things to Try

1. BIOS settings:

   • Disable PCIe power management / ASPM entirely in BIOS
   • Check for BIOS updates
   • Try different PCIe slot if available (M.2 vs dedicated)

2. Kernel parameters (add to GRUB):

pcie_aspm=off pci=nomsi

3. Check if device responds at all:
   sudo lspci -vvv -s 6d:00.0 | grep -E "LnkSta|Status" Look for "LnkSta: Speed 8GT/s, Width x1"

   • if it shows "disabled" or errors, PCIe link is bad.

4. Force device reset before driver load:
   echo 1 > /sys/bus/pci/devices/0000:6d:00.0/remove
   echo 1 > /sys/bus/pci/rescan

This appears to be either:

• Missing MT7927-specific support
• X870 platform/BIOS compatibility issue
• Hardware power sequencing problem
