I got a problem that the system is showing BMC responding ECC Un-correctable error by software watchdog timer (using Winbond watchdog driver named wbwd.ko) reset from FreeBSD9 (Hardware Watchdog timer option in BIOS setup is disabled). The same problem happens on both X8DTI-F and X8DTH-IF platforms.
Here is the test steps to reproduce the problem:
1.Download the wbwd.ko from http://www.trantek.com.au/download/wbwd.ko
2.Add this line "hint.wbwd.0.at="isa" to /boot/device.hints file, reboot and go through the following steps:
# kldload ipmi
# kldload ./wbwd (load Winbond Watchdog driver)
# watchdogd
# ps auxwww | grep watchdogd
# kill -9
