I am experiencing similar behavior on the Lichee Pi 4A with thead-dwmac. It works fine on 6.12.12 and 6.13.1, but with 6.14-rc1 I don't see these last several lines of output as in your case. I did also see the same new error: +stmmaceth ffe7070000.ethernet: Can't specify Rx FIFO size It looks like this message was introduced in the following commit and if I build with it reverted my ethernet interfaces work again. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/ethernet/stmicro?h=v6.14-rc1&id=8865d22656b442b8d0fb019e6acb2292b99a9c3c Thanks, Jason > This is the diff of the output of `dmesg | grep rk_gmac-dwmac` on 6.13.0 > and 6.14.0-rc1: > > --- m4.ok.log 2025-02-03 11:37:03.991757775 +0100 > +++ m4.nok.log 2025-02-03 11:37:17.249455484 +0100 > @@ -15,4 +15,13 @@ > rk_gmac-dwmac fe300000.ethernet: COE Type 2 > rk_gmac-dwmac fe300000.ethernet: TX Checksum insertion supported > rk_gmac-dwmac fe300000.ethernet: Wake-Up On Lan supported > -rk_gmac-dwmac fe300000.ethernet: Normal descriptors > -rk_gmac-dwmac fe300000.ethernet: Ring mode enabled > -rk_gmac-dwmac fe300000.ethernet: Enable RX Mitigation via HW Watchdog Timer > -rk_gmac-dwmac fe300000.ethernet end0: renamed from eth0 > -rk_gmac-dwmac fe300000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0 > -rk_gmac-dwmac fe300000.ethernet end0: PHY [stmmac-0:01] driver [Generic PHY] (irq=POLL) > -rk_gmac-dwmac fe300000.ethernet end0: No Safety Features support found > -rk_gmac-dwmac fe300000.ethernet end0: PTP not supported by HW > -rk_gmac-dwmac fe300000.ethernet end0: configuring for phy/rgmii link mode > -rk_gmac-dwmac fe300000.ethernet end0: Link is Up - 1Gbps/Full - flow control rx/tx > +rk_gmac-dwmac fe300000.ethernet: Can't specify Rx FIFO size > > The configration was updated with `make olddefconfig`, as usual.
