You can only run one watchdog at a time. Remove the watchdog userland
program, unload the sc520 module, insert the wd1100, start the watchdog
program. Make sure you pass enough <br>
<br>
They use the same /dev/wd handle so your wd1100 will not load. This is
a tricky thing to do, so I always compile the wd1100 from source for
your k tree. I am running this on 2.6.11.7 so if something is broken
in .12, I am unaware of it.<br>
<br>
modprobe wd1100 sysctl_wd_graceful=0 sysctl_wd_timeout=30<br>

Thanks for the help.<br>
<br>
Ok I have done this but still don't work. I ever compile everything by
myself ;-)<br>
I have removed /etc/init.d/watchdog, removed module sc520 and inserted<br>
wd1100 with "
modprobe wd1100 sysctl_wd_graceful=0 sysctl_wd_timeout=30"<br>
then done a reboot.<br>
<br>
BTW: rmmod now works fine without running sc520 ...<br>
<br>
What source of wd1100 driver do you use? Do you have running this on
wrap?<br>
The rare thing is that the reboot begins but fails with the "memory
message"<br>
i.e. first message comes<br>
640 KB Base Memory<br>
comes but second message<br>
130048 KB Extended
Memory
<br>
comes not and the system hangs.<br>
<br>
Thanks for help. I really don't know more what do to and I really don't
want to go back to 2.6.8<br>
so I have to compile every progs again ... <br>
<br>

I'me trying since days without luck to reboot my wrap wiht 2.6.12 ...<br>
With kernel 2.6.8 from voyage reboot works without any watchdog<br>
(i.e. I disabled watchdog in /etc/init.d)<br>
Only modules are:<br>
dm_mod, natsemi, crc32<br>
<br>
If I use my kernel 2.6.12 it will not reboot<br>
With sc520_wdt running it wont reboot<br>
with wd1000 (/etc/nodules) it reboots and when it is up will reboot
again<br>
If I have watchdog running wihtout wd1000 it won't reboot<br>
if I insert wd1000 (modprbe) the following message comes:<br>
<br>
wd1100: module license 'unspecified' taints kernel.<br>

I've applied the reboot patch from voyage web patch.<br>
Is this no more necessary?<br>

BTW: I don't have a /proc/sys/dev/wd/ directory<br>

Anyone using 2.6.12?
I have also tried to modify to new structure because in 2.6.12
there is the possibility to use hoocks in reboot_fixups.
Nothing worked for me. The board hangs after rebooting.
I've also tried the old reboot.c (they changed some minor stuff)
but don't work.
