ESX3.5 U2 blue screen with AMD daul core processor

We have one problem with ESX3.5 u2 booting with AMD daul core processor,when ESX3.5 initializes timer,it willreport the error as following:


TSC: 4552357591 cpu0:0)Initializing timing ...

TSC: 10150276678 cpu0:0)Init: VMKernel:718: cpu 0: measured tsc speed 2800112697 Hz, cpu speed (using TSC) 2800112697 Hz, bus speed 200008050 Hz

Could not find a usable reference timer


and after we debug we found it seems it can not initialize the ACPI PM timer and AMD daul core processor can not find the reference timer, so it will report the error.and AMD qual cores processor, it also doesn't initialize the ACPI PM timer, but it will reference the timer with TSC. So how ESX3.5 u2 detect the ACPI PM timer and initialize it? By ACPI FACT table? how ESX3.5 U2 can make AMD qual core processor can reference with TSC, why Daul processor can not?

and we have another question with ESX3.5 u2 booting when we enabled the HPET function, it will report as following;



IO-APIC (apicid-pin) 2-2, 2-16, 2-17, 2-18, 2-19, 2-20, 2-21, 2-22, 2-23 not connected.

..TIMER: vector=0x31 pin1=0 pin2=-1

..MP-BIOS bug: 8254 timer not connected to IO-APIC

...trying to set up timer (IRQ0) through the 8259A ... failed.

...trying to set up timer as Virtual Wire IRQ... failed.

...trying to set up timer as ExtINT IRQ...unexpected IRQ trap at vector 07

unexpected IRQ trap at vector 07

failed :(.

Kernel panic: IO-APIC + timer doesn't work! pester


So how ESX3.5 U2 check with these?

Thanks a lot.
