Re: [Xen-users] RAID card problem

[Yura Pismerov <y.pismerov@xxxxxxxxxxxxx>]

Thanks for response. I don't have regular (non-RAID) controller so I
can't verify whether it works or not.
Also I was not able to find IOMMU option in the BIOS.
Below is excerpt from dmesg of regular kernel shipped with Debian Etch 
(2.6.15-1).
When I boot XEN-enabled kernel (2.6.16) it  stops after the first 2
lines and does not get to the probe phase.
Same situation with Adaptec RAID card (aacraid).
I tried non-PAE Xen and kernel - no difference at this point so I assume
it has something to do with Xen.
I am totally puzzled.

megaraid cmm: 2.20.2.6 (Release Date: Mon Mar 7 00:01:03 EST 2005)
megaraid: 2.20.4.6 (Release Date: Mon Mar 07 12:27:22 EST 2005)
megaraid: probe new device 0x1000:0x1960:0x1000:0x0520: bus 10:slot 3:func 0
megaraid: fw version:[1L37] bios version:[G119]
