I grabbed the original watchdog kld from, http://freebsd.tamu.edu/wdog/ and applied the following patches --- i8xxwd.c Wed Mar 24 07:25:35 2004 +++ ../i8xxwd-current.patches/i8xxwd.c Mon Sep 13 11:02:44 2004 @@ -30,6 +30,7 @@ #include <sys/param.h> #include <sys/systm.h> #include <sys/types.h> +#include <sys/module.h> #include <sys/kernel.h> #include <sys/bus.h> #include <dev/pci/pcivar.h> @@ -48,6 +49,7 @@ {VENDORID_INTEL, DEVICEID_82801CAX, "Intel 82801CA/82801CAM watchdog device"}, {VENDORID_INTEL, DEVICEID_82801DB, "Intel 82801DB watchdog device"}, {VENDORID_INTEL, DEVICEID_82801E, "Intel 82801E watchdog device"}, + {VENDORID_INTEL, DEVICEID_82801EBR, "Intel 82801EB / ER watchdog timer" }, {VENDORID_INTEL, 0, ""}, }; --- i8xxwd.h Wed Mar 24 07:16:17 2004 +++ ../i8xxwd-current.patches/i8xxwd.h Mon Sep 13 11:02:17 2004 @@ -43,7 +43,9 @@ #define DEVICEID_82801CAX 0x2480 #define DEVICEID_82801DB 0x24c0 #define DEVICEID_82801E 0x2450 - +#define DEVICEID_82801EBR 0x24d0 + + #define SMIBASE_OFFSET 0x30 #define TCOBASE_OFFSET 0x60 #define PMBASE 0x40 Loading just this module and then using watchdogd -t 10 and then a kill -9 of the watchdogd program and the box reboots about 10 seconds later. With icwhd, no reboot.
