Sorry for the very long delay in replying to this.  I wanted to be
absolutely sure I was reproducing the bug.

Unfortunately I'm only able to reproduce the bug with qemu 2.3.0
(both the version in Fedora Rawhide, or the tagged v2.3.0 from git).

I cannot currently reproduce it at all with upstream qemu from git.

The patches understandably only apply to upstream qemu from git, and
have quite a few tricky conflicts with v2.3.0.

I'll keep trying on this one.  It may be that the window for the
bug to reproduce with qemu.git has got smaller.

Rich.

----------------------------------------------------------------------

Notes on how I try to reproduce this:

(1) Using Fedora Rawhide aarch64

(2) libguestfs checked out and compiled from git

(3) kraxel's edk2.git-aarch64-0-20150713.b1115.g2ad9cf3.noarch

(4) heisenscsi.pl (attached).

$ export LIBGUESTFS_HV=/path/to/qemu/aarch64-softmmu/qemu-system-aarch64
$ while true; do echo .; ./run ./heisenscsi.pl ; done
