I have the first significant "hanging" here: [ 7.910000] sd 0:0:0:0: [sda] Attached SCSI removable disk [ 10.810000] random: nonblocking pool is initialized [ 24.310000] systemd[1]: systemd 214 running in system mode. (+PAM -AUDIT -SELINUX -IMA -SYSVINIT +LIBCRYPTSETUP +GCRYPT +ACL +XZ +SECCOMP -APPARMOR) After booting up it takes several seconds between entering the username and the password while with version 3.15.3 the password prompt appears almost immediately after entering the username. Please tell me if some additional information is needed. Thank you very much in advance.
