+2.6.0 hangs linux vm using vfio for pci passthrough of graphics card
+
+Not a duplicate of my old bug 1488363
+
+qemu version 2.5.1 works fine
+qemu version 2.6.0 fails
+
+seabios 1.9.2-1
+
+using kernel 4.5.5 with grsecurity
+
+I built using the arch packaging tools, but commented out all the patch code, so it should be vanilla.
+
+The problem is just that I start a Linux vm using either my radeon R7 260x or radeon HD 6770, and with qemu 2.6.0, it looks normal until after the grub menu, and then the screen looks broken (with mostly black, and some pixely junk spread horizontally in a few places on the screen... first we thought maybe the monitor died). I'm not sure if it's before or only at the moment where the screen resolution changes (I could check that or record it on request). Also, the VM is not pingable and does not respond to "system_powerdown" on qemu monitor.
+
+However, the same setup works fine with windows 8. And it works fine without graphics cards passed through. A usb controller passed through works fine too.
+
+
+And then I ran a bisect...
+
+        2d82f8a3cdb276bc3cb92d6f01bf8f66bf328d62 is the first bad commit
+        commit 2d82f8a3cdb276bc3cb92d6f01bf8f66bf328d62

+            vfio/pci: Convert all MemoryRegion to dynamic alloc and consistent functions
+            
+            Match common vfio code with setup, exit, and finalize functions for
+            BAR, quirk, and VGA management.  VGA is also changed to dynamic
+            allocation to match the other MemoryRegions.

+        
+then confirm it by reverting that commit
+        git checkout v2.6.0
+        git revert 2d82f8a3cdb276bc3cb92d6f01bf8f66bf328d62
+        git mergetool -t kdiff3
+            "select all from C", save
+            not sure if this is the right way to do this...but it compiles and works (bug fixed)
+        git commit -m "revert 2d82f8a3cdb276bc3cb92d6f01bf8f66bf328d62 resolve conflicts"
+
+And that 2.6.0 build with that one patch reverted works fine.
