In my previous post, I ended with a wall: mt7925e 0000:0b:00.0: ASIC revision: 0000 mt7925e 0000:0b:00.0: Message 00000010 (seq 2) timeout mt7925e 0000:0b:00.0: Failed to get patch semaphore mt7925e 0000:0b:00.0: hardware init failed The mt7925e driver bound to the MT7927’s WiFi hardware, but registers returned zeros. The chip sat behind PCIe doing nothing. The ehausig/mt7927 project had gotten firmware into kernel memory but stalled at DMA state 0xffff10f1 - “waiting for firmware transfer.” Nobody had gotten past it. ...

Update — March 5, 2026 MT7927 WiFi now fully works on Linux - 2.4/5/6 GHz, WiFi 7 320MHz EHT (~1 Gbps), MLO, AP mode, suspend/resume, and mac_reset recovery. 20 patches, community-tested on 10+ hardware platforms. See the follow-up: MT7927 WiFi on Linux: Making It Work. In my previous post, I documented the 15-month journey to get Bluetooth working on the MediaTek MT7927. The btusb-mt7927-dkms AUR package patched three missing layers - USB device ID, hardware variant support, and firmware extraction - to bring up a fully functional Bluetooth 5.4 adapter. ...

In November 2024, I installed an ASUS ROG Crosshair X870E Hero motherboard - AMD’s flagship X870E platform with a MediaTek MT7927 (Filogic 380) WiFi 7 chip. Running CachyOS, WiFi worked out of the box through the mt7925e driver. Bluetooth did not. What followed was a 15-month journey through kernel source, mailing lists, and community reverse-engineering that ended with a working Bluetooth 5.4 adapter and a published AUR package. This is the story of how it got there. ...
