Hi,
I’m testing DietPi on a Radxa ROCK 4C+ and I’m seeing severe Ethernet instability.
The board boots and gets a DHCP address, but ping is extremely slow and unstable, with high packet loss:
rtt min/avg/max = 42/549/1311 ms
27% packet loss
SSH never completes the TCP connection and hangs at:
Connecting to 172.20.254.27 port 22
The same network works normally with a Raspberry Pi 4 running DietPi, typically below 1–3 ms latency.
What worries me more is that after a few problematic boots/reboots, the situation seems to become destructive: the board eventually stops booting at all from that SD and shows no useful network activity anymore.
I also tested the ROCK 4C+ on another LAN and at one point it did not appear on DHCP at all.
Are there any known Ethernet / PHY / kernel / boot issues with the current DietPi image for ROCK 4C+?
I can provide dmesg, ethtool, kernel version and serial console output if useful.
