* AXI-L Interface ordering - The v071417d3 shell has an issues that impacts transaction ordering on the AXI-L interfaces (BAR1, OCL, SDA) only. The Shell should preserve PCIe ordering rules on these interfaces, but there is an issue where a read request may pass a previous write request. The shell terminates a write when the data is transferred on the W channel (WVALID/WREADY) rather than wait for the response on the B channel. A CL workaround for this issue is to backpressure reads (deassert ARREADY) when there are any writes pending.

* Linux kernel 3.10.0-862.2.3.el7.x86_64. By default, the AWS Developer AMI GUI setup script updates the kernel version. We have provided a patch to prevent kernel updates during GUI setup. Instead of running the setup_gui.sh as documented/included within the developer AMI, please use the patched script as shown below:
