NAME # pwdog - Quancom PWDOG1 watchdog timer device
SYNOPSIS # pwdog0 at pci?
DESCRIPTION # The pwdog driver provides support for Quancom PWDOG1 boards.
If the kernel crashes, the watchdog timer is not reset and the system will reboot (assuming a proper connection is made between the PWDOG1 and the motherboard). Alternatively, the watchdog can be reinitialized via a userland process which ensures that process scheduling, not just kernel timeout processing, is still taking place.
