Can you give me more info?<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>
SC1x00 Watchdog driver by Inprimis Technolgies.<br>
wd1100.c: a few hacks by <a class="moz-txt-link-abbreviated" href="mailto:erich.titl@think.ch">erich.titl@think.ch</a><br>
wd1100.c: Can't register device.<br>
<br>
Which wd1100 should I use?<br>

I've applied the reboot patch from voyage web patch.<br>
Is this no more necessary?<br>
<br>
BTW: I don't have a /proc/sys/dev/wd/ directory<br>

rmmod wd1100<br>

Applying the reboot patch to 2.6.12 does not work.
After
unmounting local filesystems...done.
Rebooting... sc520_wdt: Watchdog timer is now disabled...
Restarting system.
PC Engines WRAP.2B/2C v1.04
640 KB Base Memory
the system hangs
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.
