Hyper-V freezes on my Asus P5K

I started to prepare my old desktop PC to become a development server running virtual servers on Microsoft Hyper-V.

Hardware Specifications

The hardware specification is as follows:

Motherboard: ASUS P5K

CPU: Intel Xeon X3210

Memory modules: 4×2 GB Kingston Value Ram DDR800

Hard disks: 1×120 GB Hitachi (boot), 1×120 GB Seagate, 1x Western Digital 640GB

Graphics: An old ATI GTO800

Installing Hyper-V Server

My first attempt was to install the free standalone Hyper-V Server 2008 R2.

Everything went smoothly until I connected remotely with my Windows 7 laptop and started to create virtual hard disks. The PC started to hard freeze. Ctrl+Alt+Del didn’t help, it totally locked itself.

Very frustrating. I did have some bad experience with memory modules before, so I suspected that this was a case of bad memory modules.

Downloaded Memtest86 v4.0 and let it ran for an hour. Nothing. Rock solid.

Since the problem happened during creation of the virtual hard disks, I started to suspect some I/O issue with the disks. Removed all but the boot drive and tried again. No. Hard lockups continued. Bad.

I started to run out of options now. The PC had been running Windows Vista 64bit and Windows 7 64bit rock solid, without a glitch. What on earth could cause the Hyper-V behave like this?

Installing Windows Server 2008 R2

Since the possibilities to troubleshoot is rather limited on Hyper-V Server, being console based, I decided to wipe my boot disk and install a full fledged Windows Server 2008 R2 with the Hyper-V role hoping that at least something in the event log could shed some light on the issue. Said and done.

It started good, I could create virtual hard disks and install operating systems without a glitch. I was happy.

I thought I had it going until I prepared remote management for the Hyper-V role, and connected to the server remotely….. bam! Hard freeze again.

This was not good at all. Re-booted, and tried to map a network drive from my laptop to the PC… bam! Hard freeze. Like on order.

Now I started to remember something… didn’t I actually had some network issues with the motherboard before? Indeed, sometimes the built in network card stopped working when I ran Windows Vista. A reboot didn’t always help, I was sometimes forced to do a full power cycle.

Enter the crappy Attensic L1 Ethernet controller

Reading the ASUS support forums I found out that there was a lot of people that had network issues with the built in Attensic L1 controller.

The joy of an Intel network card.

Ok, I had to find an alternative and went out and bought an Intel PRO/1000 GT Desktop Adapter, installed it, and disabled the on board Attensic controller.

Every since that moment, the PC has been rock solid. No freezes, no lockups.

 

Lesson learned: when it comes to network adapters, there is only one make that cuts it: Intel. Period.

One thought on “Hyper-V freezes on my Asus P5K

  1. I just installed 2008 r2 on my core 2 quad / p5k to run as a home media server. Same issue as you, hard lock ups.

    You’ve given me hope, I too had forgotten about the NIC issues I had with this board a while ago. I’ve got a couple of intel add in NICs and I’ll try one later!

    Hope it works!
