Yesterday evening after I left the office it froze again. I see in the
syslog up to that freezing moment:

Actually the system freezing BEFORE installing the 4.2 kernel seems to
have generated something else in the log up to that freezing moment:

swVersion="7.4.4" x-pid="977" x-info="http://www.rsyslog.com";] exiting on
signal 15.
So, before the kernel upgrade (so on kernel 3.19) it froze once with the last
message in the log:
rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="977"
x-info="http://www.rsyslog.com";] exiting on signal 15.
And after kernel upgrade ((so on kernel 4.2), each time it froze I saw
in the log as last message before freezing:
kernel: [ 3376.109135] [drm] HPD interrupt storm detected on
connector HDMI-A-1: switching from hotplug detection to polling
