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

Does the problem also happen with a vanilla kernel?

Didn't tried yet.

As I talked to my collegues we found that these bugs are someway random that it may be related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61904. Is it possible?

Kbd                    1.15.5
Sh-utils               8.21

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!
