Thanks.  These will have to wait for 1.6 though.

This should work for all current releases.

I just wanted to check in on you whether you still have this on your
radar for 1.6? I cannot seem to find any commits in this regard, yet.

Sorry for being a pain in the neck... but, since it's been two months
now and 1.6.0 is released, as well as 1.6.1 and this bug is still out
there (AFAIS, it's not fixed looking through the git history) I just
wanted to check what's going on.

Why is there so little interest in getting this fixed?

BTW, the workaround you proposed here[1] works fine for me. What's
blocking the inclusion into qemu's git?

Kind regards.

The patch is posted, waiting for review.

I prefer to get the root cause fixed.
