There is also an big increase in time before random is initialized: [ 182.811840] random: crng init done This is a machine on bare metal. On other environments like proxmox I've seen: [ 303.993638] random: crng init done Downgrading to the previous kernel resolves the problem (normally a few seconds). One of the consequences is that openntpd (or a program like rdate) hangs until the crng is initialized. R. -- richard lucassen http://contact.xaq.nl/
