kernel errors for on-board ethernet

[beepy]

Hello again,

I have the Quartz64-B v1.3

dmesg is reporting a raft of re-occuring errors with the built-in ethernet / NIC.

-These are all happening with: latest plebian, diet-pi, arch arm

[ 2777.053671] rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma
[ 2777.054322] rk_gmac-dwmac fe010000.ethernet end0: stmmac_hw_setup: DMA engine initialization failed
[ 2777.055169] rk_gmac-dwmac fe010000.ethernet end0: __stmmac_open: Hw setup failed
[ 2777.090016] rk_gmac-dwmac fe010000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0
[ 2777.185378] rk_gmac-dwmac fe010000.ethernet end0: PHY [stmmac-0:01] driver [RTL8211F Gigabit Ethernet] (irq=POLL)


as a result I cannot bring the NIC online. (tried ip link set end0 down/up and raises these dmesg output)

(fyi: if its useful, I can use an usb eth dongle and kernel recognizes it and I connect via that okay - usless it is usb3.0 port and another set of warning are raised ...for another port maybe)

I have tried using the PoE adapter I have for it and "normal" eth with DC power, and the same issue.

Any help much appreciated.
Thank you
