There's a lot of information about the WDT under the kernel Documentation directory. I think it's a software interrupt, probably difficult to raise it over hardware interrupts. If you don't want the WDT, disable it via procfs or as a boot cmdline argument. BUT, recognize if the WDT isn't serviced then something bad is going to happen somewhere else. My guess is the kernel will panic with an ENOMEM or maybe it will silently stop. Certainly no user-space application is going to run if the CPU is saturated processing interrupts. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
