I have a freshly built, updated EL6 system and am having problems with
USB stability - at boot everything works fine but within a few hours,
USB devices start disappearing randomly. At first I though the USB
devices were suspect, but removing the suspect devices and an accessory
PCIE USB card hasn't changed anything. As of now, a single USB device is
working. (which is lucky, it hosts the OS) I've rebooted the server
several times trying to diagnose the problem. After a reboot, everything
works great - for a while. Is this a driver issue or just a bum
motherboard/chipset?
The system is built based on the SUPERMICRO MBD-X9SCM-F-O available here:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813182253
According to the OS compatibility matrix, the most recent CentOS 6.5 is
supported:
http://www.supermicro.com/support/resources/OS/C204.cfm
and all yum updates have been applied.
I have the output of /var/log/messages since the last reboot here:
http://hal.schoolpathways.com/lastboot.txt
Notes: Everything was working after the boot. Devices read/wrote fine.
ata9.00 HD errors are known, it's the old ATA O/S drive.
Jun 11 01:07:36: Problem begins shortly after leaving for the day,
Jun 11 03:35:44 sdi goes offline, it's one of the two USB boot devices
and is plugged into the USB port directly on the main board. (IE: It's
not a bad cable)
Jun 11 15:53:43 b2012 goes offline, it's mounted USB.
Here's the output of lspci (Note, this is when the system is having a
problem)

I plan on verifying/updating the BIOS tonight. Is there any other
information that I could provide to help diagnose this?
