For years I had the same problem on several laptops. Without any reason, regardless of whether the computer was working intense or idle, the computer would freeze. This could happen several times a day or once a month. The Syslog left no trace. Two weeks ago it came on my mind one option in grub: acpi_osi="Linux", I inserted it into /etc/default/grub, made update-grub, and since then there was no freeze at all. Moreover, the whole computer runs faster and the CPU is less loaded.

This is an intentional decision by acpi-linux guys. A lot of firmware have completely untested and broken code under osi(linux). It goes as far as code under OSI(Linux) writing to random locations in memory corrupting whatever happens to reside there. Acpi-linux has a whitelist of machines where OSI(Linux) is enabled. However more interesting would be to fix generic code instead. In any case it has to go on acpi-linux, not here
