Xen Still hangs up when insmod xenbus.ko. Re: [Xen-devel] Unmodified_drivers modules broke again for 3.0.4?

["Liang Yang" <multisyncfe991@xxxxxxxxxxx>]

Hi Ian,

Now I can xen-platform-pci.ko can be loaded after building 
unmodified_drivers modules with the correct kernel header. Thanks for 
pointing out.
However, Xen still hangs up when I try load xenbus.ko module after 
xen-platform-pci.ko is loaded successfully. The problem remains the same 
even though I applied the patch you provided and using the latest 
xen-unstable.hg version.
Thanks,

Liang
