Compiled latest kvm-git. Now I do not try igfx_off as it is not needed to run X anymore.
I've found out that #2 is actually a combination two different issues:
2a) Sometimes (randomly) the card just do not work with none of the OS's. Same symptoms as described - detects cable but no traffic. This correlates with DMAR failures accessing the PCI bridge. Most of the time the card works with...

Update. Tested with three different Intel cards: PCI (e1000), PCI-e (e1000e) and the onboard one (e1000e). Actually, it turned out to be two different issues.
1) With intel_iommu=igfx_off, none of them are working. Did I misunderstood the purpose of igfx_off? I thought it only disables IOMMU for graphics devices. With intel_iommu=on, all of them work, but...
2) ...with the e1000 it does...

qemu-kvm-0.11 stable - same result.
Anybody managed to passthrough an Intel PCI/PCI-e NIC?.

Actually it is not a bug at all. The reason is that, by its nature, a mouse device reports only its relative movement, and not the absolute position. Therefore the guest OS has no idea what is the current cursor position in the host OS is. In contrast, a tablet device reports absolute coordinates, and this allows qemu/kvm to put the emulated cursor into the same position as the host one.
The...

Note: with intel_iommu=on, same problem.

I should note that I also tried to pass through the built-in Intel Ethernet adapter of this board and got the same.

With flow control disabled, I was not able to reproduce the issue so far.
Will wait for a patch, thank you.

The machine is a file server, and when I copy a 100 MB file from this server to a workstation over NFS (transfer rate is 60-100 MBytes/sec), I get the hang in about 10% cases.
The in--kernel driver did the same.
Sure, I'll be able to run the patched driver.
I'm attaching the files with the info you requested.
