Hey,
I'd like to ask people the following question: why are you using
compressed modules? Is it only for the disk space or is there any
performance related reason?
While fixing a bug in kmod related to using compressed modules (that
already existed in module-init-tools) we stopped to think about

Attempting an rds connection from the IP address of an IPoIB interface
to itself causes a kernel panic due to a BUG_ON() being triggered.
Making the test less strict allows rds-ping to work without crashing
