I have a Quad Opteron machine (Tyan mobo) with 32GB RAM and I can''t to get it to work with a PCI RAID card. I try it with Xen 3.0.2 (built from the source). I''ve already tried 2 different cards (Adaptec 2120S and LSI Megaraid). In both cases the boot process stops once card driver is loaded. It does not attempt to load scsi_mod and probe the scsi bus. A non-Xen kernel works fine with those cards on the same hardware. Any ideas ? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

No troubles so far. Both the on-board LSI SCSI controller and an areca 24xSATA Raid6 controller work without problems. Do you have IOMMU enabled in the boards BIOS? /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
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] Ernst Bachmann wrote:> On Tuesday 09 May 2006 00:50, Yura Pismerov wrote: > >> I have a Quad Opteron machine (Tyan mobo) with 32GB RAM and I can''t >> to get it to work with a PCI RAID card. >> I try it with Xen 3.0.2 (built from the source).

Problem solved. It turned out ACPI support was off in the kernel. Oops... Yura Pismerov wrote:> Thanks for response.
