Hi, I installed today (pushed by the software update) the kernel 3.19.0-59 and I got the same problem with it. Here is the part of the syslog around the freezing point:
May 10 11:44:27 my-ubuntu wpa_supplicant[1311]: wlan0: CTRL-EVENT-CONNECTED - Connection to 02:18:5a:8f:fe:13 completed [id=0 id_str=] May 10 11:44:27 my-ubuntu NetworkManager[1258]: <info> (wlan0): supplicant interface state: associated -> completed May 10 11:44:27 my-ubuntu NetworkManager[1258]: <info> (wlan0): roamed from BSSID 02:18:4A:8F:FC:B3 (FD_Staff) to 02:18:5A:8F:FE:13 (FD_Staff) May 10 11:44:42 my-ubuntu wpa_supplicant[1311]: wlan0: CTRL-EVENT-SCAN-STARTED May 10 11:50:36 my-ubuntu kernel: [ 2724.303310] sound hdaudioC0D0: HDMI: ELD buf size is 0, force 128 May 10 11:50:36 my-ubuntu kernel: [ 2724.303348] sound hdaudioC0D0: HDMI: invalid ELD data byte 0 May 10 11:55:42 my-ubuntu kernel: [ 3030.170491] [drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling May 10 12:32:31 my-ubuntu rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="1099" x-info="http://www.rsyslog.com";] start May 10 12:32:31 my-ubuntu rsyslogd: rsyslogd's groupid changed to 104 May 10 12:32:31 my-ubuntu rsyslogd: rsyslogd's userid changed to 101 May 10 12:32:31 my-ubuntu kernel: [ 0.000000] Initializing cgroup subsys cpuset May 10 12:32:31 my-ubuntu kernel: [ 0.000000] Initializing cgroup subsys cpu So you can see in the above log fragment the last line before freezing: May 10 11:55:42 my-ubuntu kernel: [ 3030.170491] [drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling I also tried the 4.2.0-36 kernel that was pushed today (for the duplicate bug) and got the same problem: May 10 09:17:01 my-ubuntu CRON[6013]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) May 10 09:36:50 my-ubuntu compiz: pam_ecryptfs: seteuid error May 10 10:00:01 my-ubuntu CRON[7191]: (root) CMD (if [ -x /usr/sbin/backupninja ]; then /usr/sbin/backupninja; fi) May 10 10:06:44 my-ubuntu kernel: [ 7264.163450] [drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling May 10 10:35:57 my-ubuntu rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="986" x-info="http://www.rsyslog.com";] start May 10 10:35:57 my-ubuntu rsyslogd: rsyslogd's groupid changed to 104 May 10 10:35:57 my-ubuntu rsyslogd: rsyslogd's userid changed to 101 May 10 10:35:57 my-ubuntu kernel: [ 0.000000] Initializing cgroup subsys cpuset May I please ask of a status update, please? When will this bug be fixed? Has anybody tried to look at the changes between the kernels 3.19.0-58 and 3.19.0-51 and try to figure out why is this problem happening? If so, may I please at least get a clarification here about the cause? Because at the moment I am unable to install anymore any security patched kernels that you guys are pushing.
