We are experiencing a problem with the watchdog on DH57JG motherboard that uses the H57 Express chipset. We have found that the watchdog is not resetting the system when we stop writing to the watchdog device.
We have several hundred appliances that use this board all running Ubuntu Linux 10.10, 12.04 or 13.04 (32 and 64 bit) using kernels 220.127.116.11.22, 3.2.0-29 and 3.8.0-19 respectively.
Has anyone had this issue or similar? Does anybody have this board/chipset and can test if the watchdog works under Operating Systems?
We have upgraded to the latest BIOS for this board. BIOS version is JGiBX10J.86A.0663.2011.1019.0408
Watchdog timer is a feature that comes by default and it cannot be disable, at least not with the user’s options on the BIOS.
Depending on the model number of the board you can disable this feature but the DH57JG does not come with that option. It looks like only old motherboards have this option on the BIOS such as 4 series boards.
You may want to forward your inquiry to Linux* Ubuntu distribution support community for any further assistance.
