<p>Hello.</p>
<p>I need some help. I've just installed Fedora Core 6. I was running Fedora 2 (yeah, it's been a while since I upgraded).</p>
<p>At random times, the system now crashes. Never crashed, before.</p>
<p>Then, I applied all updates, including the latest Kernel update. The computer continues to crash at odd times. Sometimes, the computer will run for hours. Sometimes, it will crash quickly.</p>
<p>I have tested memory for six hours (memtest86), no errors. I did several different tests using smartctl on the hard drive. No errors.</p>
<p>Below are various logs/dmesg text, traces.</p>
<p>If someone can help, I would greatly appreciate it. This is a server that must get back on-line soon. I just don't know where to start looking for a fix.</p>
<p>Ok, a lot of stuff in this message. Here goes:</p>
<p>dmesg:</p>
