Unless I boot with hpet=disabled, the kernel gets to... Using hpet for high-res timesource Calibrating delay loop... And sits here for a few minutes, then oopses (jpg attached). This is 100% reproducible. This is a Tyan K8W dual Opteron m/b running a vanilla 2.6.8.1 kernel compiled 32bit for K8 with smp and preempt. HPET is enabled in the (latest) BIOS Anything else I can supply, let me know. Andrew Walrond
