From 61b7b67df2ed10ff5ab0dcc649080bca782fdc5e Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 1 Feb 2012 20:31:37 +0100 Subject: i8254: Do not raise IRQ level on reset Avoid changing the IRQ level to high on reset as it may trigger spurious events. Instead, open-code the effects of pit_load_count(0) in the reset handler.
