New to Unraid.  Setup server yesterday, upgraded to 6.4.0 a few hours ago after parity drive finished.  'Fix Common Problems' plug in notified me that I had call trace details in the system log.  Bit rusty, need some help interpreting before I start copying over to the Array.  Have attached the diagnostics package as well.  Other then create some empty shares and install some plug-ins, I haven't done anything else yet.

Try looking for a BIOS update

Jan 13 19:48:00 Tower kernel: Your BIOS is broken; DMAR reported at address 0!

But if you don't see any adverse affects, ignore it.
