I have 2 systems based on this MB.<br>

System has 2 128GB SSD drives.<br>
<br>
Running CentOS 6:<br>
<br>
2.6.32-431.20.3.el6.x86_64<br>
<br>
Before vacation I placed one of my management devices with this system and configured serial terminal. I got this working.<br>
<br>
The odd behaviour came on reboot. When I issued a reboot the last message on the serial console was "Restarting system". The system appeared to hang. If I restarted via the reset button the system may not boot. I would see the BIOS post on my LCD, but nothing when accessing the SSD. I ran out of time so I rigged up X10 control so that from PCB I could cycle power. The only way I could get it to boot when i experienced this behaviour was to pull power. X10 solved it.<br>
<br>
I had done some much, upgrade, add PCI card, etc that I decided to narrow it down before I left. When I disabled serial console in Grub and the OS problem went away. My conclusion was that this problem may not be specific to the Linux kernel, but something about the hardware on the MB. The BIOS does support console redirection, but I've yet tested it to see if that fixes the problem.<br>
<br>
I run my system headless at Peak 10 using serial console so not having a serial console on this one makes me nervous. I have power control there too so I only visit to touch hardware.<br>
<br>
This is the first time I experinced a problem like this that was linked to running serial console in Linux.<br>
