Helios64: Armbian 25.2.3 bookworm (6.12.18) @ OMV7 - 2.5Gbit LAN -> upload to client very slow

[greg396]

If I transfer from Helios64 2.5Gbit Port to a client 2.5Gbit port I'll got a very slow transfer rate (Helios -> client around 200Mbit/s), vice versa full speed, switch is 2.5Gbit (Rj45 ethernet Cat7 cable).Testet with iperf. The switch monitoring indicates always 2 errors.

I know about the Hardware issue of Lan-Port2, but it only effect 1Gbit transfer. Nevertheless in the Network are also mixed with 1Gbit clients.

Is there anything I'll can try to get full 2.5Gbit speed?

Today I did also the hardware fix for the 2.5Gbit Port & I can confirm nothing changed concerning the speed:

Helios64 -> client around 200Mbit/s

Client -> Helios64 2.35Gbit/s but unstable connection compared to 1Gbit Port, the transfer drops

The switch monitoring indicates now 1 error.

 

My Conclusion for 2.5Gbit Port: Not usable at all!

Hi greg396,

 

solutions for your issue were discussed in the parallel thread:

 

You need to update the rtl_nic firmware in /lib/firmware/rtl_nic and use the modified dtb for stability reasons.

 

If there are any remaining problems, check the load distribution on your helios64 and the connection to your client. 

 

The iperf3 transfer speeds from helios64 to macos clients in our network are 280MByte/s without any dropouts (linux 6.6.87 is recommended), upload speed is around 230MByte/s and we are using it 24/7 without any issues.

Dear ebin-dev,

the rtl_nic firmware from your link are already in /lib/firmware/rtl_nic - anything I should do?

the modified dtb for 6.12 are installed already in march - without any changes.

Your suggestion should be to downgrade the kernel, but how can I downgrade from actual kernel 6.12.x to your recommended deb-package 6.6.87 without getting into trouble and how I should disable kernel updates?

@greg396  You can downgrade linux to 6.6.87: unzip the file debs-6.6.87.zip on your helios, cd into the folder and submit  'dpkg -i linux*'. With linux 6.12. I get some timeouts during data transfer. You need to install the modified dtb for the linux-6.6 branch in /boot/dtb/rockchip/  (do not forget 'update-initramfs -u' after that and reboot).

 

Follow the link load distribution and Install the code displayed ('cd ... exit 0') in /etc/rc.local and reboot.

 

I have disabled any Armbian updates by commenting the text in /etc/apt/sources.list.d/armbian.list but submitting 'apt-mark hold armbian-firmware' may work as well.

 

However, I have no idea whether or not OMV requires a specific kernel branch - but I don't think so. If you need to reinstall linux 6.12. you can collect the three corresponding deb packages (linux-image, linux-dtb and linux-headers) on http://beta.armbian.com/ (currently 6.12.25).
