This error happened when the MMIO of assigned device is not page aligned. Here MMIO size of your device is 0x20 Bytes. The commit fb48c7c858cc612e3e1cb011c534075ac5de553d in kvm userspace should fix it. Was it included in your userspace?
Thanks for your answer!
How can i check if the commit is included? And where to checkout the
latest snapshot?
I am using kvm-84 sources from sourceforge and kernel 2.6.29rc6 on
ubuntu 8.10

The commit changes rom bios, you can use "make bios", and "make install" to make it take effect. And I think replacing "-net nic,macaddr=52:54:00:58:08:03 -net tap,script=/etc/qemu-ifup" with "-net none" will also work for you.
Regards,

making and installing bios done - no changes.
with "-net none" it WORKS! Bud i need network... i´ll try to passthrough
my Intel PCIx NIC too...
Already tried:
- remove not needed-parameters
- dma=none
- set assign-device DEBUG (as you see)
Additional Info:

Can you post output of "lspci -v"? We can see if its mmio is page aligned or not. Can you check if commit fb48c7c858cc612e3e1cb011c534075ac5de553d was included in your kvm-userspace?
