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