This was already fixed in staging by "x86/crash: fix kexec transition breakage": https://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=f56813f3470c5b4987963c3c41e4fe16b95c5a3f Looks like it needs inclusion into 4.11 branch. -- Thanks, Sergey _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
