Hello, Everyone
I just ran "yum update" and rebooted.  Some time not long after that
reboot, I started getting message like this:
Dec 22 20:11:26 afolkey2 kernel: [ 4130.161465] BUG: soft lockup - CPU#3 stuck for 22s! [httpd:1889]

I ran "grep -i "soft lockup"" with the following results:

[root at afolkey2 log]# grep -i "soft lockup" messages

I rebooted into an older kernel and have not had any more of these
messages popping up.

Eventually, my system became unresponsive and I had to reboot.

I am running Fedora 20 (fully updated)
Installation method: fedup

Any ideas?
