When a processor is brought offline and online again, it is unable to use Turbo mode because the _PSS table does not contain the whole turbo frequency range, but only +1 MHz above the max non-turbo frequency. This causes problems when ACPI processor driver tries to set frequency constraints. See patch 2 for more details.
