Seems PAGE_ED is likely on in lookup_domain_mpa... BTW, bit[53-63] are ignored bits per 4.1.1.5 of SDM2, and then you can just ignore them instead of BUG there. ;-) Thanks, Kevin _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel |
