PCI-passthrough fails with Ubuntui kernel 3.5 and above

Description

Hi, was using PCI passthrough since 1.5 years. Host Ubuntu 12.04 with kernel 3.2.x, VB different versions (4.x to 4.3.4). After upgrade to raring kernel the PCI-passthrough fails. Trying kernel 3.5.x showed the same. The PCI device is one of the USB controllers on the mainboard. The fail situation prevents the windows7 in guest to start the root hub driver (error 43). BTW: USB passthrough is not an option to what I need to achieve. It is too slow if USB devices re-enumerate after a firmware flash, so I cannot debug firmware flashers.

Attachments: syslog and VB log for both kernels, and guest.vbox. I can do tests if you need that.

Hi, tested with saucy kernel (3.11), still does not work. I had hoped for some improvements with that kernel since the change log contains quite some lines talking about IOMMU fixes.

If there is anything I can do myself, please let me know.

PS: If you are still in Endersbach, then I can bring the machine for some test if you need that.
