Xen devel - Nov 2007 - xenbus_printf causes system reboot in kernel module

I used

xenbus_printf(XBT_NIL,"mydir", "command", "%s",
"do_something");

in my kernel module, which causes my system to reboot.

Do I miss something, like initialization code before this call?

Thanks,
Weiming

Is the mydir+command or do_something more that 256 chars long?

no, just those literal strings.
if the dir/node does not exist, xenstore should create them.
I also tried existing dir/nodes, no success.
