RE: [Xen-devel] 2.6.32.27 dom0 + latest xen staging boot failure

["Kay, Allen M" <allen.m.kay@xxxxxxxxx>]

The machine is an Intel Sandybridge Desktop SDP (Software Development Platform).

Setting 'dom0_mem=max:1024MB' worked.  Booting with "dom0_mem=max:512MB" 
panic'ed in mount_block_root().

Ok, then it probably is related to the issues we had with the P2M
or MFN list being incorrect... and your E820:

is like swiss-cheese with the RAM regions.
What machine is this and how can I get my hands on it?

Does it boot if you have 'dom0_mem=max:512MB' (it is important
to have the 'max' there)?
