Hello,
Environment: Seabios master dd9bba5b9c1d5175a2757f3fdc9d554b4c8eea3a Qemu: 1:2.5+dfsg-5ubuntu10.14 OS: Ubuntu 16.04
We found that newest Seabios (dd9bba5b9c1d5175a2757f3fdc9d554b4c8eea3a) is not working with latest Fedora 26 - image taken from: https://download.fedoraproject.org/pub/fedora/linux/releases/26/CloudImages/...
Each time it hangs on "Probing EDD (edd=off to disable)... OK".
We discovered that rollback to version 4902b8a7 solves the problem. It seems that something is wrong with 4902b8a7. After fetch lastest master and rollback of 4902b8a7 - Fedora is able to boot.
Ubuntu is booting all the time without problem.
Could you take a look on this?
Thanks. I do see a defect in 4902b8a7 - it is not generating linesize correctly (see patch below).
