Right. Well, I will try to reproduce with the BB white I have.

Yeah that should be reproducable, I got it to happen on BBB here
after about 5 boots.

Are you booting with an initrd?

Not on this one, on beagleboard xm I do.

Interesting.

Then loading modules with CONFIG_RANDOMIZE_BASE=y seems to fail with:

$ sudo modprobe rtc-twl
rtc_twl: disagrees about version of symbol module_layout
modprobe: ERROR: could not insert 'rtc_twl': Exec format error

Is this with CONFIG_MODVERSIONS enabled?

Yes, but disabling that did not seem to make any difference
based on just one test.

Yeah, well, it appears I missed a couple of details :-)

This should fix the module loading issues:

Yeah now modprobe works :) That's after manually applying
it as the tabs got munched in your patch somewhere, see below.

Yeah, Gmail tends to do that now and again. Apologies.

Thanks for confirming that the module loading works for you, I will
fold this into my v3.
