Hi everyone,
I'm been trying the latest SVN versions of coreboot-v3, OpenBIOS and Qemu together and I am experiencing a panic on boot when launching qemu-system-x86_64. I can see some hardware enumeration but before the OpenBIOS prompt appears, qemu puts out the following message on the console:
qemu: hardware error: register_ioport_write: invalid opaque
As far as I can tell, I don't think that it's a qemu issue since qemu SVN successfully boots with the pre-built coreboot-v3/OpenBIOS image found at http://www.coreboot.org/QEMU#coreboot_v3_.2B_OpenBIOS, which suggests that the bug lies somewhere between OpenBIOS and coreboot.
I've uploaded the full console output to http://pastebin.siriusit.co.uk/coreboot-v3-panic.txt in case other people may find it useful.
ATB,
Mark.
