Re: [parisc-linux] case LEDs

I think that the heartbeat LED is software because it starts with the kernel
boot and if the kernel stops the LED stops
blinking too. Is better to implement a software monitoring tool because you
have to watch the software for hanging.

PS. There is a function in the kernel source in
linux/arch/parisc/kernel/process.c named machine_heartbeat(). Any connection
with the heartbeat from the chassis?
