[CentOS] Hardware watchdog timer, no IPMI, no /dev/watchdog

Hi all,

I've got a Portwell NANO-6060 board I am testing out for potential use in a project of ours. One of the nice features of this board, beyond nice NICs, is that it has a hardware watchdog timer.

The problem is that I don't get a /dev/watchdog device file. I know the hardware works, because when I enable it in BIOS, the box will reboot after the timer expires. However, without the /dev/watchdog device, I don't have a way to kick it.

In dmesg, I see:

NMI watchdog enabled, takes one hw-pmu counter.

So it *looks* like it's there. Also, I installed the 'watchdog' package (but not the IPMI package) and the watchdog service is running.

Any tips?

Thanks!
