From a6f4e3cf75538a75ee4fab620e3c8466f2154458 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 25 Jun 2005 14:55:22 -0700 Subject: [PATCH] [PATCH] uml: fix timer initialization In skas mode, the call to uml_idle_timer permanently shut off the virtual timer, resulting in no timer ticks to anything but the idle thread. This is likely the cause of the soft lockups that are seen sporadically in recent UMLs.
