Dell PowerEdge R900 freezes / locks with Windows Server 2008

We have 3 Dell PowerEdge R900 running Windows Server 2008 they started to freeze at random (it did not blue screen). We have sent Dell and Microsoft a memory dump use the Non-Maskable Interrupt (NMI) on the front of the server.

Microsoft came back saying that the megasas.sys is the problem, this driver is used for the Dell PERC 6/i to run the local hard disk in the server (we had a RAID 10 layout). The PERC is made for Dell by LSI Logic Corporation.

I have asked Microsoft to remove the Dell R900 for Windows 2008 from the Windows Server catalog.

We have spent many weeks working with Dell to fix this problem but they still have not come back with a fix. LSI has to rework the drivers. In the mean time Dell said to change the control but we have reinstalled under Windows Server 2003 and the servers are looking happy.

Photosynth Outside My Home In London

So I was looking at Scobleizer blog and he blogged about Microsoft PhotoSynth. I tried it out from on the courtyard outside my home in London on the last sunny day on Summer 2008. But are watching a video it looks like can get a lot more complex.

I am going to make a more complex one later, but you can check out my current one at http://photosynth.net/view.aspx?cid=79245027-407b-40b8-85fb-fcd985a123f9
