Looking at the various syslog files we have, it seems we always get messages similar to those :
Apr 21 23:02:11 kernel: [ 1072.770546] Clocksource tsc unstable (delta = 182801418122 ns) Apr 21 23:02:11 kernel: [ 1072.774264] Time: acpi_pm clocksource has been installed.
Those usually appear at the same time as the installer get stuck.
