Network Problems

Rock Pi 4 1.72 @ kernel 5.10.63

cma: cma_alloc: alloc failed, req-size: 2 pages, ret: -12
cma: cma_alloc: alloc failed, req-size: 2 pages, ret: -12
rk_gmac-dwmac fe300000.ethernet: Failed to reset the dma
rk_gmac-dwmac fe300000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
rk_gmac-dwmac fe300000.ethernet eth0: stmmac_open: Hw setup failed

What does this mean? And what can I do to fix it?

Could it have something to do with this?

Which kernel are you using? Self built one or the one from Debian. We need to check the dts.

Maybe best to continue in Rock Pi 4B+ (1.72) Ethernet Speed
