Is there some critical section where "xm pause" might cause a lockup?
When I run FreeBSD to some point (I don't know where - the console
isn't giving output) - and then pause it, the machine locks up. I
can't even get info from xen apart from switching the switching the
serial input.


kmacy@siml4 ssh moe
kmacy@moe xm list
Name              Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0           0      507    0  r----     54.5        
xen-vm2            1      128    1  r----      0.1    9601
kmacy@moe xm pause 1

Note that this is with domu_debug = n.

The changeset I'm using is from the -unstable on the 11th.
