[Xen-devel] xsa46-4.2.patch breaks PCI passthrough?

[Steven Haigh <netwiz@xxxxxxxxx>]

Hi all,

I've had a report lodged against my packages that the patch provided for 
XSA46 against Xen 4.2.1 causes PCI passthru to break.
It seems that 4.2.1 *without* the XSA46 patch works perfectly. 4.2.2 
does not work.
I added this patch in xen-4.2.1-6 of my RPMs (http://xen.crc.id.au) and 
the reporter has built the same SRPM with xsa46 patch removed and PCI 
passthrough works as intended.
Reapplying the XSA46 patch causes it to break again.

The bug report and logs can be found here:
        http://xen.crc.id.au/bugs/view.php?id=5

Has anyone come across this?
