Watchdog hardware usually works by causing a reset if it doesn't get poked in a given time interval. Since there's a kernel driver involved I assume that's the case here. If the freeze, be it kernel or user space, stops the watchdog being poked then you get a restart. You may be seeing the kernel continue while the glamo freezes. Or I may be making the wrong assumptions about how this watchdog works ;-) _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
