From 2b79aac9038ee52fd8d89216b1a3ec9bd8285fac Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 19 Feb 2008 18:58:49 +0000 Subject: MN10300: Call update_process_times() outside of the xtime_lock Call update_process_times() outside of the xtime_lock. Somewhere somewhere inside one of the functions called by that, xtime_lock is readlocked, which ends up in a deadlock situation.
