From f793a3581901ff39c2abb94012d9bbc8573ccf02 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 16 Apr 2008 22:57:58 -0700 Subject: [PATCH] avr32: Disable the AP7000 internal watchdog on startup This patch forces the watchdog off in all cases. That will at least get rid of the constant reboot cycle, though it won't let the watchdog actually run in the new kernels: its probe() comes up with a polite warning.
