Resolved Issues from v1.2 to v1.2.1

Table 6.  Issues Resolved from v1.2 to v1.2.1 of the Intel Acceleration Stack Software
Issue Description
Invalid memory read fault may cause FIM to lock.
  • Running an AFU at this instance might return accelerator not found. The fpgainfo error indicates Non-Fatal and CompStat error (completion status error).
  • The FIM locks after the AFU sends a memory read to invalid address.
  • Workaround: Power cycle the system to reinitialize the Intel® PAC with Intel® Arria® 10 GX FPGA and recover from this issue. Refer to the Knowledge Base entry for more information.
  • Status: Fixed in the Intel® Acceleration Stack v1.2.1.
Possible corruption of board management controller firmware during an in-band update.
  • The board management controller firmware may be corrupted when performing an in-band update using fpgaflash. This event prevents the Intel® PAC with Intel® Arria® 10 GX FPGA from booting after the update.
  • Workaround: The current installer implements a workaround that checks for data corruption and retries an update up to three times. If the update continues to fail after the three attempts you must relaunch the fpgaflash command without rebooting your host.
  • Status: Fixed in the Intel® Acceleration Stack v1.2.1.
The BMC may return incorrect sensor data.
  • The BMC may return incorrect sensor data to the pacd and fpgainfo tool. This incorrect data may cause pacd to interrupt the execution of applications using the Intel® Programmable Acceleration Card (PAC) resulting in a system reboot.
  • Workaround: No workaround available.
  • Status: Fixed in the Intel® Acceleration Stack v1.2.1.
