Re: [Xen-devel] hvmloader crashed when passthrough bridge device but not intel piix4 acpi pm

[lcy985a <lcy985a@xxxxxxx>]

In my case, this PLX bridge must work with some special software which can't 

run on domain-0。So I have no  choice without passthrough it.

I'm not sure are there some other devices working similar with this bridge,

And not sure it is  suitable for others.

Just deal with the one  I faced.
