I build kernels with MODULE_SIG=y, MODULE_SIG_FORCE=n (for build and run coverage, but it shouldn't dork my system if it breaks). next-20150810 works just fine, but next-20150826 breaks modprobe - all calls to it drop this in the dmesg:
[ 31.829322] PKCS7: Unknown OID: [32] 2.16.840.1.101.3.4.2.3
[ 31.829328] PKCS7: Unknown OID: [180] 2.16.840.1.101.3.4.2.3
[ 31.829330] Unsupported digest algo: 55
and the modprobe fails.
This looks like the most suspicious commit in the area:

MODSIGN: Extract the blob PKCS#7 signature verifier from module signing
though it could be something else equally recent. Is this ringing any
bells, or should I go bisect it?
