Hello, When having high traffic on the MPC5200B ATA (MWDMA2), FEC (100MBit) and LPC (MTD FLASH read) I will get the typical FEC_IEVENT_RFIFO_ERROR's.
Without the FLASH reads, that we use to stress the probably existing LPC arbiter or MPC5200B silicon bug when running UDMA2+LPC, and which should not happen using MWDMA2+LPC, I could not yet reproduce the FEC_IEVENT_RFIFO_ERROR. Now comes the problem: since the PHY driver rework followed by John Bonesio's fix (rev 37ccd92f55c6c6) to avoid accessing the DIO bus at interrupt context, this now sometimes causes an irrecoverable link down (PHY: f0003000:00 - Link is Down). This patch is of course necessary to avoid a panic. I can reproduce that on the current DENX/master using an own board very close to the Lite5200B. This board runs fine under the old 2.4.25, of course also sometimes showing the FEC FIFO error. Any ideas?
