The last set of changes in Jeremy's kernel are a set of patches I sent, so the problem is most likely caused by my work. A dmesg from both Xen and Linux kernel would be most helpfull. Also a lspci -vvv would be nice. And as Pasi suggested, booting the same kernel without Xen would be most helpful. > > dom0_mem=4096M works > dom0_mem=4097M fails with stacktrace > > Boris: What was the last kernel that worked without backtraces? > Also, does that same kernel work as baremetal (without Xen) ? </div></blockquote></td></tr></table>
