If it was software induced it was caused by http://logs.test-lab.xenproject.org/osstest/logs/103741/test-xtf-amd64-amd64-3/info.html http://logs.test-lab.xenproject.org/osstest/logs/103737/test-amd64-amd64-xl-xsm/info.html (merlot0 and merlot1 respectively) Both are Xen boot failures in xen-unstable. The former failed with a Xen panic (see below). The latter also with a similar-looking panic. I have noticed a tendency for boot order to be corrupted in situations where Xen on the hard disk crashes on boot. Or rather, when I find that I am resetting the boot order, I disproportionately often find that the host in question is in a crash/reboot loop. Ian.
