Thx.

So this thing is not completely quiet:

# dmesg -l err,warn,notice -x
...
kern  :notice: [   17.974749] random: dd: uninitialized urandom read (512 bytes read)
kern  :notice: [   18.063596] random: dbus-daemon: uninitialized urandom read (12 bytes read)
kern  :notice: [   18.065212] random: dbus-daemon: uninitialized urandom read (12 bytes read)
kern  :notice: [   20.161303] random: crng init done
kern  :warn  : [  144.505690] umip_printk: 403267 callbacks suppressed
^^^^^^^^^^^^^^^^

so at least it says that umip is being busy logging stuff and if one
wants to see them, one can do:

# dmesg -l err,warn,notice,debug -x
kern  :notice: [   17.974749] random: dd: uninitialized urandom read (512 bytes read)
kern  :notice: [   18.063596] random: dbus-daemon: uninitialized urandom read (12 bytes read)
