Gluglug X200 hangs on boot after `# guix system reconfigure /etc/sysconfig.scm', right after starting dmd

[白い熊]

I've installed GuixSD on the Gluglug X200 without a problem, using instructions 
for the X60. [1]

Did `# guix pull' and reconfigured the system to enable the wicd service. [2]

However on the Gluglug X200 the system freezes upon reboot with a kernel panic 
if “(wicd-service)” is included in services in sysconfig.scm, same symptoms 
upon boot crash as another user has experienced with the X200. [3]

The current kernel is 3.18.9.

If sysconfig.scm contains: 

(use modules (gnu))
(use-service-modules xorg networking dbus avahi)
(use-package-modules avahi wicd)
...
(services (cons* (slim-service)
                 (dbus-service (list wicd))
                 (dhcp-client-service)
                 (avahi-service)
                 %base-services))

the system boots no problem after reconfigure. However wicd can't be started 
even with the dbus-enable hack [4], as the “wicd-service” is logically not 
present, and thus “sudo deco enable wicd” fails with “No service at all 
providing wicd.”

Now when just “(wicd-service)” is added to services, this being the only change 
compared with the above, the system will hang on boot.

There are no error messages on boot up to dmd start. Then it fails with:

I'll be much obliged for help in getting wicd working on the Gluglug X200. 

Best regards,
