Re: [Xen-users] Soft Lock on cpu problem Still???

[Xin Chen <xcheney@xxxxxxxxxxxxxx>]

Hi,

Thanks for that!

Just wondering, isn't kernel-xen a product of XenSource? If the redhat 
kernel-xen is not working, can I just use the XenSource one? Is the 
XenSource Kernel-Xen not working in fedora, so redhat has to develop it 
themselves based on XenSource one. or did XenSource ask redhat to 
develop the kernel-xen for fedora? I just don't understand. As this bug 
has been fix in XenSource, right? I was thinking about not using the 
redhat kernel-xen, use XenSource kernel-Xen may fix the problem?? Can 
anyone help me clear about this? Sorry for my english..
Now I am gonna to downgrade the kernel to 2.6.19. Thank Pasi :)

cheers,
x
