I have been digging through the git rep of ubox, and I have built every version from the last 2 months until the version which is now referenced in the LEDE source.git. This is what I found (the date is the commit date):

ubox_2016-12-04-acc48b55-1_mips_24kc.ipk - xfrm_algo loads fine
ubox_2016-12-19-db070f15-1_mips_24kc.ipk - xfrm_algo loads fine
ubox_2016-12-19-8488bb5b-1_mips_24kc.ipk - xfrm_algo loads fine
ubox_2017-01-15-eacc4261-1_mips_24kc.ipk - xfrm_algo loads fine
ubox_2017-01-15-46a4b5f7-1_mips_24kc.ipk - xfrm_algo loads fine
ubox_2017-01-15-a62c946e-1_mips_24kc.ipk - router failed to boot - needed failsafe and firstboot to get back.
ubox_2017-01-15-93714117-1_mips_24kc.ipk - router failed to boot - needed failsafe and firstboot to get back.
ubox_2017-01-15-6e3c6dcf-1_mips_24kc.ipk - "kmodloader: failed to find dependency xfrm_algo"
ubox_2017-01-15-14839f0a-1_mips_24kc.ipk - "kmodloader: failed to find dependency xfrm_algo"
ubox_2017-02-01-f8d3d167-1_mips_24kc.ipk - "kmodloader: failed to find dependency xfrm_algo"
ubox_2017-02-01-ac2d43e7-1_mips_24kc.ipk - "kmodloader: failed to find dependency xfrm_algo"

So, the bug lies in one of three commits:
a62c946ecdced9468ad16738325ee322029b0476 kmodloader: modprobe: skip possible command line arguments
9371411715c8dd882f1d65a712f1f38b6d38d01f kmodloader: fix out-of-bound access when parsing .modinfo
6e3c6dcf922e30282d2c49a643253e58fffab362 kmodloader: add module alias awareness

That is as close as I can get, I am not a debugger :) I just have some git knowlegde and I like to test LEDE.
