[Xen-devel] Bugs in 2.6.31.12-pvops

["Carsten Schiers" <carsten@xxxxxxxxxx>]

Hi,

honestly, I am a bit unsure, whether what I do is correct. I hg cloned 
current xen-4.0-testing, 
which will build the 2.6.31-12 kernel out of the box. I build that 
kernel and let in run on my 
Xen 3.4.1 hypervisor. config was what approximately comes with default 
values, because I have 
not a lot of knowledge with configs.

Kernel started with one WARNING message:

[    0.000999] WARNING: at

Hope this helps. 

BTW: Can someone please tell me how to test xen/stable-2.6.32.x? Is that 
by changing in the mk.linux-2.6-pvops xen/master
into 2.6.32.x?

Which one should I use for testing?

BR,
Carsten.
