| SFP peer to peer between two EPYC 3000 is not working.                                                   |
| Reboot test fails at ~30 cycles.                                                                         |
| Transfer rate is very low (3.63Gb/sec) on both kernel for 10G peer to peer (Switch) scenario with iperf. |
| I2C3 fails to operate at FM+ (1000k) and 100k speeds.                                                    |
| Not able to install ubuntu 18.04.1 emmc server OS on eMMC (all modes).                                   |

## Known Issues
| # E3000 Known Issues/Limitations #                                                                                                                   |

| Bandwidth drop observed when running all ports simultaneously with default system configuration and the solution is system level tuning is required. |
| Peer to peer network between EPYC 3000 Series CPUs (using xgbe) is not working with few finisar SFP modules.                                         |
| FIO Sequential Read/Write ZE3351HAQCAAF_30Performs better than ZE3451HAQGAAF_30.                                                                     |
| FIO Random Read/write performance for QD32 BS4k is low compared with spec.                                                                           |
