8.2 releng

Dear Sean,

I've investigated the problem, and found the following:

When starting with
# xm create -c /dev/null kernel=/home/krichy/kernel extra="kern.hz=100" 
memory=464

The kernel boots up, but when adding only one more MB to it, as:
# xm create -c /dev/null kernel=/home/krichy/kernel extra="kern.hz=100" 
memory=465

it does crash.

The config is the simple one I've attached previously, with pf and pflog 
disabled. But again, if I enable pf and pflog, the domain starts with 
512MB ram well.

Regards,
