[coreboot] Net and virtio problem with QEMU 0.10.0 and coreboot v2

[rukhsana ansari]

Hi,

Software used :
qemu-0.10.0, coreboot-v2, filo(latest svn version), fedora9 image

Problem encountered:
qemu boots Fedora9 image successfully. However, the ethernet interface isn't
up and dmesg shows an irq problem.

Thhings tried out:
I've tried pci=biosirq and problems still remains.
I've also patched with the qemu bios patch (0.9.1) available at:
http://www.mail-archive.com/coreboot@coreboot.org/msg01771.html
However, I haven't applied the other patches that are meant for 0.9 and
available at

ttp://www.coreboot.org/QEMU_Build_Tutorial#Building_Qemu
<http://www.coreboot.org/QEMU_Build_Tutorial#Building_Qemu>
because the code difference with 0.10.0


Any suggestions from coreboot experts on howto proceed to resolve this issue?

The following is an edited version of dmesg that shows an irq problem:
