The hardware power management in the T7500 causes the random crash and freezes. When the machine changes between the ACPI "C" power states (Intel TurboBoost/Intel PowerStep) the entire machine will freeze and become unresponsive. Kernel newer than 2.6.29 have some code that helps, but the issue still is not solved even in kernel 2.6.34.

You must _disable_ all power management features in the BIOS of the T7500 for stable operation.
