RE: Reboot on *DOM0* while/after installing GPLPV drivers

[John Hayward <john.hayward%wheaton.edu@localhost>]

I think this patch fixed the disk driver failure to prevent crash of dom0 but 
did not address the underlying problem of the driver to properly register.  I 
have not had time to verify this.

While installing the net driver I also don't have networking after install on 
win7 - I do see an error in 
starting win7 on NetBSD-5.1.2 dom0 of:
====
xenstore-read: couldn't read path /local/domain/0/backend/vif/22/0/vifname
====
This occures both before and after I install the pci and network drivers.
Before install of network drivers windows reports a realtek ethernet device
After install of network drivers windows reports Xen Net Device Driver
It does have the correct mac address.
The interface does not get an IP via dhcp - if manually configured it still 
cannot ping the default router for the network it should be on.

I get the same with 7 and Windows 2012 64.. Also the network driver
installs but I have no network at all.
