From 80354c29025833acd72ddac1ffa21c6cb50128cd Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Sun, 12 Mar 2017 17:07:44 +0200 Subject: [PATCH] x86/platform/intel-mid: Correct MSI IRQ line for watchdog device The interrupt line used for the watchdog is 12, according to the official Intel Edison BSP code. And indeed after fixing it we start getting an interrupt and thus the watchdog starts working again: [ 191.699951] Kernel panic - not syncing: Kernel Watchdog Signed-off-by: Andy Shevchenko Cc: Borislav Petkov Cc: David Cohen Cc: H.
