Hi, Very bad news:
Latest security patch for kernel 3.19.0 (that is 3.19.0-58) which I installed today automatically through updates, freezes my laptop again with the same "HPD interrupt storm detected on connector" error that I was getting with the 4.2 kernel: Apr 6 14:46:17 xxx-ubuntu dbus[1001]: [system] Activating service name='org.freedesktop.hostname1' (using servicehelper) Apr 6 14:46:17 xxx-ubuntu dbus[1001]: [system] Successfully activated service 'org.freedesktop.hostname1' Apr 6 14:46:17 xxx-ubuntu kernel: [ 945.147481] systemd-hostnamed[11982]: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolveable. Plea se install nss-myhostname!
