[Xen-users] kernel 3.x and Intel SRCSASPH16I a. k. a. LSI Megaraid SAS 84016E

[Daniel <dandadude@xxxxxxxxx>]

Hi Everyone!

I have got a problem I have been dealing with for many weeks now.

I have a Supermicro server with an Intel SRCSASPH16I RAID-card (which is also known as LSI Megaraid SAS 84016E, just with Intel BIOS installed).

Now my basic problem is:

I can install all kind of linux distros without a problem, but when I install the xen stuff, the system does not boot up, it has problems with the disk. The distro I know it works flawlessly is with CentOS 5.x with 2.6.18 kernel.
The distros it had problem with: OpenSUSE 11.4 (2.6.37), OpenSUSE 12.1 (3.x.x), Debian Squeeze (2.6.32), Debian Wheezy (3.x.x).
The weird thing is that everything is fine until I boot up the xen stuff, so without the xen stuff, evertyhing boots up OK. In the 3.x.x kernel distros this is really frustrating, because there the kernel includes the xen code, so only xen.gz can cause such problems. It can't be a driver problem, altough I wanted to try to install the new drivers from Intel and also from LSI, but it seems that 3.x.x kernel is not supported.

It has got this card with lspci:
03:0e.0 RAID bus controller [0104]: LSI Logic / Symbios Logic MegaRAID SAS [1000:0411]
05:00.0 SCSI storage controller [0100]: LSI Logic / Symbios Logic MegaRAID SAS 8208ELP/8208ELP [1000:0059] (rev 08)

Here are some screenshots of my experiments. I have tried with ext2 all, ext3 all, btrfs all, ext4 all, lvm or without lvm etcetc...
