Hi @Sand_Death, Thanks again for identifying the MSI issue. I've just updated my branch with some MSI-related changes. I tried to align the implementation as closely as possible with the Raspberry Pi 5 PCIe driver. Could you give it a try and let me know whether it resolves the issue on your end? I'm now seeing additional MSI interrupts being generated by my NVMe drives. https://github.com/alexcaoys/allwinner-bsp/commit/a9eaa51dace582a15b1a3a7380f588cd31e06a54#diff-63112d28b443d435556e546cdc59423df248d8f963a80b15680a52ae67f1cf1c That said, I still believe there are some significant issues in the PCIe driver. For example, I think it causes my NVMe SSD to overheat when used with a board also based on the ASM1182e. Please keep an eye on whether you observe similar behavior with your Hailo-8 as well. If the HAILO_DRIVER_TIMEOUT issue still persists after testing this change, could you also attach your dmesg output? Thanks!

@Nick A Thanks that's interesting to see! I don't have a Cubie board to test with but I will look at those scripts for signal of what else can be shared as common between the boards. I think the mainline work you are doing (along with linux-sunxi's work) are definitely the long term solution.

Yes, but now, I'm trying to make Bluetooth work and put Armbian to boot from eMMC. But I don't know exactly how to correctly submit these changes.

@XFer012 Here's a patch of the changes @stary presporak made to the decompiled DTB. Trying to create a patch using the original DTS but I don't have much free time right now. changes.patch

@Julio Cesar Goldner Vendramini Are you planning on submitting this to Armbian as a PR so it gets included?
