RE: [Xen-devel] Re: Xen pv kernel (2.6.30) causes s2ram to crash with segmentation fault

[Kamala Narasimhan <Kamala.Narasimhan@xxxxxxxxxx>]

Do you have a mixed 64b xen/ 32b dom0 stack?  If so, it is quite possible 
vbetool was not built to use the right emulation library.  Like I mentioned in 
an earlier thread, XCI build tree takes care of issues of this kind.  You might 
want to use that or build vbetool with the right emulation library and hope no 
other component in your environment is impeding S3 or causing further issues 
with respect to host S3...
