Nothing to do with modutils.  There is currently a test in fault-armv.c
to detect mis-reported alignment faults on the ARM720 core.  The test in
previous kernels was a little over-zealous in that if you did an ldrb
to a page which wasn't in core, and the ldrb was misaligned, it would
spit out this complaint.

There is a fix in test11-rmk1 which checks the instruction before
complaining.
