Subject: Cannot start up HVM guest when maxmem is not equal to memory and HAP is enabled.

Hi all,
On my production deployment with xen-3.4.4-rc1, HVM guest would not start
up when maxmem is set not equal to memory, unless HAP is disable(hap=0).
The guest just hangs at 'Booting from Hard Disk...' as shown in the
attachment. I find that both Oracle VM and Fedora have the same problem per
the following links:
http://docs.oracle.com/cd/E15458_01/doc.22/e15443/toc.htm#BABBIBFD
http://docs.oracle.com/cd/E26996_01/e18546/CJAGDAGB.html#id419003
https://bugzilla.redhat.com/show_bug.cgi?id=645319
Could I ask if there is any work in upstream/xen-unstable to fix this
problem?
Thanks.
Below is the xm dmesg output related with the hvm guest:
