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.

Things 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 of  the code difference with 0.10.0

Any help is greatly appreciated.

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