Fixed the network issue by removing the net udev rule, somehow that was causing the network no to come up. Disabled iscsid since it's not needed and added did echo 0 > /proc/sys/kernel/hung_task_timeout_secs to fix the megaraid issue. -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Paul A Sent: Friday, April 13, 2012 3:41 PM To: 'CentOS mailing list' Subject: Re: [CentOS] upgrade issue Mark, I used the centos repos, this server has centos 5.8.

I wanted to switch back to the previous kernel but for some reason the network scripts hangs even though it shows the e100 nic driver loaded. -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of m.roth at 5-cent.us Sent: Friday, April 13, 2012 3:31 PM To: CentOS mailing list Subject: Re: [CentOS] upgrade issue Paul A wrote: > Dale, I disabled it and the server came up but im seeing all sorts of > kernel errors when its disabled ( see below ).

Oh, wonderful. Didn't used to see that before the last six months. <snip> > Apr 13 15:21:31 bakup kernel: Call Trace: > Apr 13 15:21:31 bakup kernel: [<f89aa522>] megaraid_queue+0x8ce/0x8d8 > [megaraid] <snip> Interesting. Is this built-in for CentOS, or did you install megaraid from other than the CentOS repositories? mark _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
