I'm running into a similar issue with a Debian6 system fully updated (standard and -updates repos). It's an IBM x3850, 16G of ram I tried setting max_dom0_mem like stated here [1] but didn't solve the issue, the server reboots after scrubbing free ram. Still hadn't chance to connect a serial console.
I also tried setting: GRUB_CMDLINE_XEN="dom0_mem=512M dom0_max_vcpus=1 dom0_vcpus_pin" but no go. Any other possible workaround? I few months ago I installed two other servers with Debian6 and much more ram and didn't face the issue.
