Critical Issue
Description
Due to a problem in the 1.0 release of the Intel® Acceleration Stack for Intel® Xeon® CPU with FPGAs, if the AFU reads host memory at an invalid address then the FPGA stops responding.
Resolution
Verify your AFU is reading a valid host region. See Shared Memory APIs for a description on how to allocate and share system memory with an AFU. See the hello_fpga code example, which shows you how to use these application programming interfaces (APIs).
If this condition occurs, a power cycle of the system is required to recover.
