Re: [Xen-users] Problem with secondary sata controller

[Casey DeLorme <cdelorme@xxxxxxxxx>]

It could be unrelated, but check your `dmesg` or `xl dmesg` for "DMA Read" errors.

If you find it you may have to search for additional information:

It's a bug with certain SATA controllers, I have experienced it with both Marvell and ASMedia controllers.

I am having problems getting my 64-bit Debian Squeeze (Xen version 4.0, Linux Kernel 2.6.32) dom0 to recognize a harddrive connected to a secondary sata controller. My motherboard is a Gigabyte GA-X79-UP4 and has two sata controllers. The first is controlled by an Intel X79 chipset and the second is controlled by a Marvell 88SE9172 chip. During the initial install of Debian everything is fine and I can see harddrives attached to either controller. If I boot Xen from grub, I cannot see the harddrives on the Marvell chip, if I just boot the stock Debian kernel I can see the harddrives. The Marvell controller shows up in lspci. I tried to do a pci passthrough of the Marvell controller to both a PV and a HVM domU, but it didnât work.
Is this a known issue? Would upgrading my kernel help? Would upgrading Xen help?This message and any attachment are intended solely for the addressee and may contain confidential information.
