Why xen 3.4.x doesn't works on server with this controler Symbios Logic SAS1064ET PCI-Express Fusion-MPT SAS

[Albert <forall@stalowka.info>]

I'm testing now xen 3.4.1(stable) and I testing before when is come a 
stable. I'm having problem with controller driver, he can't load itself 
properly so the system isn't booting. The system is debian 5.0 with 
kernel 2.6.26-2-xen from distribution  the problem occure with both kernels

ouput from debian 5.0/kernel 2.6.26-2-xen/xen-3.4.1

If anyone had the same problem with mtpsas driver and xen 3.4. What has 
been changed so it's not working on upper xen version.

  The problem doesn't occure with xen 3.3.x
