Visit your motherboard manufacturer's website or use the Intel Driver & Support Assistant to ensure your chipset drivers are current. This often resolves the "missing driver" status for system devices. 2. Check BIOS Settings
Some benchmarks suggest that the overhead of calling the HPET (which involves a system bus transition) can cause "micro-stuttering" compared to the CPU's internal Invariant TSC (Time Stamp Counter). Academic Context: Real-Time Systems Kernel Latency
Why disable HPET on Linux? On some older chipsets (AMD SB700, some Intel PCH families), the HPET driver causes a —thousands of unwanted interrupts per second, locking up the system.
