Okay that makes things more difficult.

Unfortunately that is not even the first Ooops. So there should be
more earlier already in the log. Are you able to provide the full
kernel log from once the problem is happening?
If the system is not accessible anymore, then consider attaching a
netconsole so we get logs from as early as possible from boot and then
logged over the network.
The full log would be better, if not, then at least we should get the
first oops and see from there.

This sesm quite an old system, nwer BIOS version seems available still
slightly more recent taht the 07/15/2016 version, so you might
consider updating it.
