qemu-system-x86_64 -soundhw all […] fails for me: qemu-system-x86_64: /var/tmp/portage/app-emulation/qemu-1.6.0/work/qemu-1.6.0/ioport.c:240: portio_list_add: Assertion `pio->offset >= off_last' failed. It seems that this was already fixed upstream: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=2b21fb57af305f17841d79e7e2e02ad1 Not sure whether you want to add this patch in a revbump of the 1.6.0 ebuild, or whether you'd rather wait for the next release. In any case, having this bug documented here might help others who experience the same. Workaround for users (thanks to epatch_user): # mkdir -p /etc/portage/patches/app-emulation/qemu-1.6.0 # wget -O /etc/portage/patches/app-emulation/qemu-1.6.0/adlib.patch \ 'http://git.qemu.org/?p=qemu.git;a=patch;h=2b21fb57af305f17841d79e7e2e02ad1' # emerge -1 qemu After this, qemu booted fine.
Fixed by app-emulation/qemu-1.6.0-r1 due to a patch called 0023-adlib-sort-offsets-in-portio-registration.patch
