Re: [Xen-users] xen i/o errors

Hello,

Additional information about your hardware might help others debug the situation.

What version of Xen are you using?  Are you compiling or is it from the package manager?

I have experienced a DMA READ issue before but I have no idea if it is relative to your configuration.  Something to do with a Marvell SATA controller and intel's IOMMU, which was optional when compiling the kernel but required fror VT-d/IOMMU Passthrough.

I don't know if that is much help to you, but feel free to add more system information to help everyone debug.

Hello,
I've been trying to setup xen on Debian Squeeze but it isn't going that well.

When booting with the xen/hypervisor kernel the system hangs with i/o
errors thrown in console. The standard kernel is working fine and the
disk has been tested and swapped.
Errors include:
ata1.00: failed command: READ DMA
task xend:1404 blocked for more than 120 seconds
Buffer I/O error on device sda1
end_request: I/O error, dev sda
