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
