I did see boot attempts fail with randomize enable where no output
was produced. It seems this is happening for me maybe 1 out of 5 boots.
Enabling DEBUG_LL did not show anything either.

Yes. I am looking into a couple of kernelci boot reports that look
suspicious, but it is rather difficult to reproduce, for obvious
reasons :-)

Which hardware are you testing this on?

For testing on omap3, I'm mostly using logicpd torpedo devkit as
it works out of box with PM with mainline Linux and has NFSroot
usable too.

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.
