I hope this is the right place for such a finding. If not, please forgive me. My Orange PI Zero 3 got upgraded to Armbian 26.05 yesterday. Usbip modules are gone: Using armbian 26.05: ls -l /usr/lib/modules/$(uname -r)/kernel/drivers/usb/usbip ls: cannot access '/usr/lib/modules/6.18.33-current-sunxi64/kernel/drivers/usb/usbip': No such file or directory After downgrading using armbian config to linux-image-current-sunxi64=25.11.2 (v6.12.58) Note: Armbian 26.02 is not available via armbian-config. ls -ld /usr/lib/modules/$(uname -r)/kernel/drivers/usb/usbip drwxr-xr-x 2 root root 4096 Jun 14 00:11 /usr/lib/modules/6.12.58-current-sunxi64/kernel/drivers/usb/usbip As soon as it becomes available for the officially supported odroidc2, I will test, too.

@alexc Hi, thanks for the response and for the patch! Just to clarify — we actually used your PCIe BSP fix (commit a9eaa51d) and the stock, unmodified hailo_pci 4.21.0 driver from the official Hailo GitHub (v4.21.0 tag). No changes were made to the Hailo driver side at all. Earlier in the process we had experimented with workarounds on the Hailo driver (INTx bypass + polling thread), but those were reverted completely before the final test. The report describes the end state: your kernel patch + stock driver. Result with your fix: hailo 0000:04:00.0: Enabled MSI interrupt No INTx fallback, no polling. Load average dropped from 18+ to ~12, Frigate CPU from ~485% to ~83% (real inference on 9 cameras). Regarding the GitHub PR / kernel patch — that would be great. The fix is clearly in the right place (PCIe driver), and a proper patch submission would help other Allwinner A733 users with PCIe devices.

There is only this overlay for vendor kernel: /usr/lib/linux-image-6.1.115-vendor-rk35xx/rockchip/overlay/radxa-zero3-rpi-camera-v1.3.dtbo The mainline based kernel, what you use, there is none. So you would need to port it, from this radxa03 SBC or look at other devicetree overlay files, maybe from RadxaOS, maybe from RPiOS See 'man dtc' as a start, it might be a complete renaming of a lot of the .dtso file is needed, maybe it is just an enable line.

I put image 7.1 for humanus here but now it ihas been removed due to running of space on my drive

@Sand_Death Really interesting read! Would it be possible to submit these changes through GitHub or as a kernel patch? We'd love to see the full context of the changes—the code actually provides such a clear picture of what's happening (even more so than the docs!), so a proper review of the diff would be great. EDIT: Looking at the description, it seems Claude addressed the issue on the Hailo driver side rather than fixing it in the PCIe driver. Personally, I don't think that's the ideal approach, since the BSP PCIe driver appears to be the root cause. If you get a chance to try my patch instead, I'd be interested to hear how it works for you.
