I can successfully trigger Alt-SysRQ using the serial console with a
non xen environment.
But I was not able to trigger Alt-SysRQ with xen using the serial
console.  Probably something related to hvc0?  Would be great to make
it work.

I moved the box from datacenter to the office.  I did reboot a lot of
times and no issue anymore.
I noticed that when the box was in datacenter, 3ware battery
temperature state flapping from normal to high (there are three
states: normal, high and very high).  Just guessing: if reboot happen
when in high temperature state then it hangs. Probably with a poweroff
battery state resets and this explain why never hang at first boot.
Just a guess... or maybe an electrical contact gone away moving the
box.
Maybe you have a better explanation for this strange behaviour
Thanks
