Very interesting featu= re. I just did a clone of the current qemu-kvm (which I use) and started to=20 bisect, but got an error, where I don't know how to proceed: erik@debian:~/qemu-test/qemu-kvm$ git bisect good qemu-kvm-0.14.0 You need to start by "git bisect start" Do you want me to do it for you [Y/n]? erik@debian:~/qemu-test/qemu-kvm$ git bisect bad qemu-kvm-1.0 Bisecting: 2043 revisions left to test after this fatal: Entry 'roms/seabios' not uptodate. Cannot merge. erik@debian:~/qemu-test/qemu-kvm$ Any ideas? I did a git pull, but I just got the response that it is already up to da= te... Best regards, Erik
