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.

Mark, I used the centos repos, this server has centos 5.8.
Iscsi will work on my previous kernel but not on the new one. 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.

Dale, I disabled it and the server came up but im seeing all sorts of kernel errors when its disabled ( see below ). If this can't be fixed I would really like to boot the previous kernel however the network script won't start. Im not really sure how upgrading the kernel caused the network to stop working on the previous kernel.

Oh, wonderful. Didn't used to see that before the last six months.

<snip> Interesting. Is this built-in for CentOS, or did you install megaraid from other than the CentOS repositories?

You did not fix a megaraid issue, you stopped logging it.
