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. >=20 > dom0_mem=3D4096M works > dom0_mem=3D4097M fails with stacktrace >=20 > Boris: What was the last kernel that worked without backtraces?=20 > Also, does that same kernel work as baremetal (without Xen) ?
