| 1 | | No, you can run an SMP kernel without a PSD. But of course, you will only get to use the BSP and none of the ASPs. But it surely looks that running the SMP kernel with a PSD (OS2APIC.PSDD or ACPI.PSD) is preventing the traps. I guess that OS2APIC.PSD will set CR0.NE very early in the boot process. For ACPI.PSD I could ask the developer and find out if it also explicitely sets CR0.NE. I have now readded OS2APIC.PSD to config.sys and enabled "I/O APIC" in the VM configuration. At the same time I have only enabled one CPU core (of two CPU cores available) in the VM configuration because mouse tends to get jerky with > 1 CPU core. I will see if this eliminates the traps on the long term. |
