WATCHDOG i6300ESB doesn't reboot the machine

[Ralf Hildebrandt]

I recently installed the watchdog package along with the i6300ESB
module. I killed the watchdog process and waited for the reboot. To no
avail. Is my test flawed? I even stopped the watchdog process,
unloaded and loaded the i6300esb module: No reboot. 

This is an HP-Server.

dmesg output:

[  140.017922] i6300ESB timer: initialized (0xf86cc000). heartbeat=30 sec (nowayout=0)

lspci -vv output:
