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)
