[Xen-users] 2.6.30.4 pv_ops on Debian 2.6.26 dom0 ?

["Olivier B." <xen.list@xxxxxxxxx>]

Hi,

so I have an other problem : I can't make 2.6.30 linux boot on my Debian 
amd64 dom0 (Xen 3.2.1). DomU crash at start, and "xm dmsg" report that :
> (XEN) Unhandled page fault in domain 239 on VCPU 0 (ec=0000)

I'm not sure it's same problem as on the xen-devel list : 
http://lists.xensource.com/archives/html/xen-devel/2009-05/msg00115.html
If it is same problem, what are my solutions ? Vanilla 2.6.29.6 doesn't 
work because of a bug in kernel 
(http://lists.xensource.com/archives/html/xen-bugs/2009-04/msg00005.html).
Thanks,
Olivier
