Recent regression: segfault on startup with -snapshot
As of git revision 041ccc922ee474693a2869d4e3b59e920c739bc0, qemu segfaults on startup when I try to boot a hard disk image with the -snapshot option.
To reproduce:
wget http://wiki.qemu.org/download/linux-0.2.img.bz2
bunzip2 linux-0.2.img.bz2
qemu-system-i386 -hda linux-0.2.img -snapshot
When I run this, qemu-system-i386 crashes with a segmentation fault. This is on a Debian 7 amd64 host.
git bisect implicates the following commit:
commit a464982499b2f637f6699e3d03e0a9d2e0b5288b

rcu: run RCU callbacks under the BQL
This needs to go away sooner or later, but one complication is the
complex VFIO data structures that are modified in instance_finalize.
Take a shortcut for now.
