Hello,

What is the module of your raid card ?
If it is "megaraid_sas", please try upgrading the version of that module
(see others post in the ML).

Hi All,<br>
<br>
Running xen 4.0.1-rc6, debian squeeze 2.6.32-21.<br>
<br>
In a voip setup, where I have forwarded the onboard NIC interfaces<br>
through to domU using the following grub config:<br>
<br>
module =A0/vmlinuz-2.6.32-5-xen-amd64 placeholder root=3DUUID=3D25c3ac79-68=

day before I get &quot;offline device&quot; errors. Rebooting the machine f=
ixes it<br>
straight away, and everything is back online.<br>
<br>
What in the Xen pciback is causing the raid card to go offline? The<br>
only devices hidden are the 2 onboard NIC&#39;s.<br>
<br>
I know that this issue is with Xen, as I had this running on a different<br=
>
server (same xen setup) and it had the same issues, which I initially<br>
thought were to do with the raid card.<br>
<br>
Is there known issues in this kernel and xen version with pciback? I&#39;m<=
br>
going to update to the current package versions this evening (4.0.1-1<br>
and 2.6.32-27) however would appreciate if anyone has any other insight<br>
into this issue, or even just a note to say it is a bug that has been<br>
fixed in current versions!<br>
<br>
Thanks,<br>
Mark<br>
