After lots more boots .. I found out sometimes it gets to :

..

[    4.656826] Key type dns_resolver registered

..

next line(s) in all my logs would be :

..

[    4.657507] microcode: sig=0x106a5, pf=0x1, revision=0x19
[    4.658678] microcode: Microcode Update Driver: v2.01 <tigran@...azian.fsnet.co.uk>, Peter Oruba

..

so maybe some sort race in microcode code ? but this would be strange ?
