2.
Watchdog timer failed on last boot, intermittent error message
displayed during POST
Problem
The Intel® Server Board SE7520BD2 has been found to intermittently
manifest the following false error message during boot:
Error (8190): Watchdog timer failed on last boot.
The error message falsely conveys that the board failed to execute
BIOS code and failed to disable a timer before expiration.
Intel found that this false error message is caused by the onboard
platform instrumentation not consistently recognizing the BIOS
command to disable the timer. This anomaly is present on the server
boards with FRU/SDR version BD-6.2.1 and prior. Currently, the Intel®
Server Board SE7520BD2 is shipping with FRU/SDR version 6.2.1 pre-
installed from Intel’s factory, version 6.1.3 of the FRU/SDR is also
included on the Intel Express Installer CD (P.N. C60160--002) shipped
with the board.
Workaround
FRU/SDR version BD-6.4.1 has been developed to address this
anomaly on the Intel® Server Board SE7520BD2. The FRUSDR 6.4.1
is now available at
http://support.intel.com
. All customers should refrain
from using the FRUSDR available on the Intel® Express Installer CD
and should update the server board with the version available from the
Intel web site to prevent this anomaly.
Status
Current boards are shipping with FRU/SDR version BD-6.5.1 pre-
installed from factory and with an updated Intel® Express Installer CD.
