[CentOS] FW: upgrade issue

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.

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

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