Try upgrading to the latest kernel. -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of tblader Sent: Tuesday, March 17, 2009 9:05 AM To: CentOS mailing list Subject: [CentOS] syslog: CPU stuck for 10s! Hi All, I have a Centos 5 box serving NFS3 shares from an LSI megaraid card. The box has been up and down for about a week and trying to figure out what's up. Found a syslog message today about "APIC error on CPU" and after rebooting with NOAPIC, I now get this: # cat /var/log/kernel | grep BUG Mar 17 09:51:05 ofdmz kernel: BUG: soft lockup - CPU#0 stuck for 10s! [migration/0:2] Mar 17 09:52:21 ofdmz kernel: BUG: soft lockup - CPU#0 stuck for 10s! [ssh:3491] Anyone know what this means? I found a thread* from 2006 on this list that mentions updating the bios, but thought I would get a message out early in case this doesn't fix it.
