We are currently testing the kernel version, lf-6.1.55-2.2.1 from the linux-imx repository. But we are encountering an issue with the ethernet driver, Realtek R8169, when connecting via SSH. This driver is working on older version which is rel_imx_5.4.70_2.3.7.
The chip we are using is i.MX6 Quad.
Here is the kernel message encountered.
