So now I've got a dump of /proc/modules from 16.04.4 (4.13) and the issue is
much more apparent:

** Also affects: linux (Ubuntu)
Importance: Undecided
Status: New
** Summary changed:
- Problem with plainbox-provider while running canonical-certification-server
on 18.04 / s390x
+ /proc/modules has Null references causing python parsing issues
** Description changed:
+ EDIT: this originally looked like some sort of regression in the
+ module_resource script of plainbox-provider-resource, however, on diving
+ in a bit it seems the root cause is that /proc/modules in 4.15 is
+ different than in previous kernels.
+
+ This is a line from 4.15's /proc/modules data:
+ e1000e 249856 0 - Live 0x (null)
+
+ And this is the same module info from 4.13:
+ e1000e 249856 0 - Live 0x0000000000000000
+
+ That null character at the end appears to be causing the script to
+ choke.
+
+ For that reason, because /proc/modules has somehow changed to include
+ null references (0xNULL is invalid, where 0x0000000 is parsable), I've
+ added a kernel task to this bug.

running canonical-certification-server on Ubuntu Server 18.04 on s390x
