// updateTachometers. At least that is the case with an SSD and a valid pre-linked
// kernel, along with kernel cache enabled. This 1000ms sleep seems to fix the problem,
// enabling a clean boot with TZSensors enabled.
//
// On the ProBook this is the case with both TZSensors and PTIDSensors, although
// PTIDSensors can be avoided by using DropSSDT=Yes (because PTID device is in an SSDT)
//
// And in the case of TZSensors it even happens (intermittently) without kernel cache.
