Sorry for upping an old discussion but it seems that the problem with the
bcrm47xx watchdog wasn't fixed ever.

Recently I had compiled the firmware for my D-Link DIR-320 using trunk rev.23109
snapshot. Playing with watchdog driver showed that it actually don't work.
Symptoms are much the same as ones that were reported by Stefan Monnier.

After killing watchdog process all I get in dmesg is:
...
...
bcm47xx_wdt: Unexpected close, not stopping watchdog!
bcm47xx_wdtWatchdog will fire soon!!!

The unit itself remains functional: I can ping it, access through ssh, e.t.c.
Looks like that for a some strange reason hardware reboot doesn't happen.
I don't think that using the supplied patch is the right solution as it is
pretty the same as if I would use the software watchdog driver.

It will be great if other owners of devices based on Broadcom bcm47xx platform
would check if the hardware watchdog is working as it should with their routers.
I think that having properly functional hardware watchdog is very essential part
of production-quality firmware.
