Comment 10 for bug 1908512

Via server backports [1] I was trying the version of Groovy "in place"
I expected the change to be in qemu, so I updated just the qemu components from 1:4.2-3ubuntu6.10 to 1:5.0-5ubuntu9.2~backport20.04-202011301725~ubuntu20.04.1.
Same error on 5.0 still.

I still had a qemu 5.1 for Hirsute at [2] that tried next.

Note: a praise to the neat co-installability of libs in Ubuntu/Debian - apt-cache policy was rather crowded now :-)

Trying qemu 1:5.1+dfsg-4ubuntu1~ppa4 still failed.
Trying qemu 1:5.2+dfsg-2ubuntu1 still failed as well.

All other components are still mostly on the level of Focal.
Ok, assumptions be damned - it seems to be something else than qemu.

Next best guess - the bios.
Trying seabios 1.14.0-2 + qemu 1:5.2+dfsg-2ubuntu1 then worked.

Downgrading qemu back to Focal at 1:4.2-3ubuntu6.10 but keeping seabios at 1.14.0-2 then still worked. 1.14.0-1~backport20.04-202010240636~ubuntu20.04.1 is only a minor change away and also working fine.
So the fix is solely in the seabios component it seems.
