hi guys

I've one box where I just yesterday upgraded Centos. I 
wonder if that kernel upgrade process might somewhat 
After that upgrade UEFI boot fails with:

Failed to set MokListRT: Invalid Parameter
Something has gone seriously wrong: import_mok_state() failed
: Invalid Parameter

Has anybody seen that? And maybe know to fix it?
many thanks, L.
