With boot parameter acpi_osi="!Windows 2012", this issue seems to disappear.
Test environment:
A06 / 12.04.4 + v3.11.0-{14, 15, 17, 20}
A06 / 12.04.4 + v3.12.{14, 16, 18}
A06 / 12.04.4 + v3.13.{8, 9, 10, 11}

PS: This issue can be reproduced on those kernel versions without acpi_osi boot parameter.
