# Known Issues

* For EDF 26.06 release, ethernet_performance for DHCP address assignment and SFP+ test suite yields performance lower than
80% of the maximum bitrate. Due to this, Ethernet Performance tests for DHCP address assignment case and SFP+ are expected
to fail.

* For `kr260-bist` firmware a synchronous abort kernel trace is observed which is a known issue because of the XXV IP.

  The reason being, when the link is not connected, the clock becomes unstable, and the block lock register of the XXV IP becomes inaccessible and results in a crash. [Solution/Workaround](https://adaptivesupport.amd.com/s/article/000037700?language=en_US)

* On 26.1 EDF images, a kernel call trace related to the AXI Ethernet driver is observed in dmesg when the BIST overlay is unloaded (dfx-mgr-client -unload <id>). This has been observed on KV260, KR260, and KD240 boards. Although the call trace is reported, it does not impact the execution or functionality of the BIST application.

* During Kria BIST execution, a DeprecationWarning related to the deprecated pkg_resources API may be displayed in the test output. This warning does not affect test execution or the validity of the test results and can be safely ignored.
