I'm trying to install Xen3 on a server, but I can't make the MegaRAID 
driver work.

I've installed Debian Sarge, the stock kernel ( works perfectly 
with the hardware. The SCSI RAID driver is megaraid.

Hardware is :

- IBM eServer xSeries 330 server
- Dell PowerEdge RAID II controller

I've recompiled the xen dom0 kernel ( to include the legacy 
megaraid driver instead of the new one. Now, the server freezes when 
booting (and reboots within minutes); the last lines displayed are 
these ones :

megaraid: ABORTING-1 cmd=12 <c=0 t=0 l=0>
megaraid: ABORTING-1[d7] fw owner

The default xen kernel doesn't boot either, it doesn't recognize the 
megaraid controller.

Is anybody able to help me ? Thanks !

NB : Before having the hardware RAID controller, I installed Xen3 with 
software RAID on the same hardware (with an Adaptec aic7xxx), it worked 
very well.
