[SOLVED] Kernel Panic randomly on 2 units (rPi 1 model B)

[syco]

Does anyone know the last good working
kernel version before those freezes/crashes?
I am on 3.17.something with both Pis.

I must admit, that problem is killing now
for some weeks the good daily experience
with both my Pis and I would like to get
that back.

Or are the old kernels not suitable for the
new Kodi? Is it sure, that the problem has
to do with the kernel and not the new Kodi
system?
