Oddly enough, I'm seeing much the same thing om my firewall, a
headerless 333MHz PII. However:

* I am running FC2.

* I do not have prelink installed.

* I do have tripwire, which has a daily cron job which is similarly
  disk intensive.

I just did a manual run of tripwire, and at the same time I ran
"iptables -L" from another login. The system locked up, same symptoms.

I'm not sure when I started seeing this lockup. However, the tripwire
job usually mails its results to my desktop. The first of those to not
show up is on 15 July. The machine has crashed almost every morning
since 23 July. Here is my yum.log from the last two updates prior
to 15 July:

One of the updates is a new kernel. I'm going to try running the prior
