Subject: Sudden kernel panics on AMD Opteron platforms with hardened kernel

Hello,

i'm facing sudden kernel panics. Last one happened few minutes ago. Unfortunatelly only output that i've catched is limited thanks to low resolution of console screen. See screenshot attached.

Below is output of the ver_linux script.

Linux aq 3.14.12-hardened-r2 #1 SMP Tue Jul 22 18:47:50 CEST 2014 x86_64 AMD Opteron(tm) Processor 6376 AuthenticAMD GNU/Linux

Kbd                    1.15.5
Sh-utils               8.21
Modules Loaded

Can you please point to me to a right direction where to start with debugging of this panic? It is badly reproducible because it happens randomly.

Hope you'll find all info attached.

Thanks for any help!
Jan
