Date: Tue, 24 Nov 2009 10:12:40 +0200 From: Ozan Çağlayan <ozan@...dus.org.tr> To: linux-kernel <linux-kernel@...r.kernel.org> Subject: [BUG 2.6.30.9] Soft lockup CPU#X stuck for Y seconds! Hi, We've hit soft lockups on a 2.6.30.9 KVM guest over an HP DL580-G5 host running a 2.6.30.9 kernel as well. After the soft lockups, system time skewed back in time: ~ $ LC_ALL=C date Mon Feb 1 00:10:58 EET 1954 I'm attaching the dmesg containing the two consecutive soft lockups. One seems related to cpuidle and the other to the virtio network stuff. Thanks.
