BL490g7 crashes on XENserver 6

[CaseyC]

We have 4 bl490g7 blades we have been trying to get to work with XENserver 6 for a while now.

The issue is that under load the blade will crash and the VMs will freeze.  We then have to reboot the blade.

We have tried:

Different mezanines

Booting from SDcard

Booting from SAN

A different fibre switch

Different cables, and GBICs etc

Before we were trying SSDs and they were not working.

C states and turbo mode are off as well as power savings.

I found some logs during the time of the last crash:

Anyone running XENserver 6 on these blades?

I know this is an unhelpful reply but it's always worth posting your enclosure and server firmware revisions..

Just seen another post elsewhere indicating driver requirements on g7's with certain ilo/fw configs.
