This looks like a crash, in which case the interesting parts would be
above the hex - which you didn't copy very accurately.  If possible,
using a serial console will be helpful in getting the text without
needing to retype output.

The most important part is the value of RIP and the backtrace (if one
is present); log messages leading up to the crash may also be useful.
