I have a linux image for arm board that I've created with buildroot, the image uses a kernel 4.12.7 based kernel with out of the tree patches an out of te tree gpu module. all gets compiled well and the system boots ok.
but for some reason, I think the probe part doesn't works, for example the gpu module is loaded but I don't see any detection result. e.g. no specific gpu prints and no sysfs data population.
another example is a usb dongle that gets detected if it is plugged at boot but it doesn't gets detected if I plug it while the system is running.
even if I load all the required modules, it still stays undetected.
the system is sysvinit + eudev based.
any ideas what it can be?
