After many contradictory tests, because not reproducible, the only solution that works on all the laptop where appeared the problem, is to install the latest kernel 4.4.0.130.136 (proposed) and to uninstall the package "intel-microcode" and replace it with a dummy package to prevent the installation of intel microcode, which seems not functional in some cases. This workaround is far from optimal in terms of updates, but seems to solve these wired errors.
Hello,
After many contradictory tests, because not reproducible, the only solution that works on all the laptop where appeared the problem, is to install the latest kernel 4.4.0.130.136 (proposed) and to uninstall the package "intel-microcode" and replace it with a dummy package to prevent the installation of intel microcode, which seems not functional in some cases. This workaround is far from optimal in terms of updates, but seems to solve these wired errors.
Best regards,
