Re: [Xen-devel] Unstableness in grant table block drivers

I build xen-unstable nightly and install it completely to my test box.
My configs between dom0 and domU are always identicle except for
priviledged domain.

My scenario is building the default configs either as UP or with adding
in CONFIG_SMP.  The resule is always, dom0 will boot, domU will not.
domU fails with not finding /dev/console and no root device.

I use loopback device mounts exported as /dev/sda1.

As soon as I turn off CONFIG_XEN_BLKDEV_GRANT in dom0/U configs,
the domU boots properly.

I build with debug=y and I can generate any sort of dump or information
you need to track this down.  Let me know what you need.
