Can you post a picture or transcript of the kernel panic?  Please also
include your system configuration and some information about the
hardware you are using (i.e. laptop model).

The default kernel in Guix is the latest and greatest, but you can
choose to use one of the LTS releases that are available (4.4, 4.9, 4.14
or 4.19) by adjusting the 'kernel' field of your system configuration.

Try pulling the power instead of shutting down...  :-P

(on a more serious note, it could be interesting to see if holding
AltGr+SysRq and typing 'reisub' also triggers this problem, and at which
letter).
