From 082f2c1cc7aa7aabdbf5235b788ff42e10abb399 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 10 Jan 2006 16:59:04 +1000 Subject: [PATCH] [PATCH] m68knommu: set irq priority/level different for each ColdFire serial port Set the hardware interrupt priority to a different value for each attached ColdFire serial port. According to the CPU documentation you should not use the same combination of level/priority on more than one device. People have reported odd serial port behavior with them set the same.
