Hi Srikanth,
We were able to reproduce the problem. We are still not sure why our CI did not
catch this. We will investigate and fix it.
In the mean time, please try this patch [1].
Also for more details regarding our current analysis of what happened please
read this thread from the RT mailing list [2].
I also read the thread you started on the RT mailing list. I'm not sure why and
how adding CONFIG_MODULES to the check helps here. [3]
Could you please test the patch. I did compile test and link test it but it would
be even better if you could run it.
Cheers
