I don't have nearly enough info to file a proper bug report.

I am running qemu-kvm-0.13.0 rc1
starting qemu like so:
/root/qemu/bin/qemu-system-x86_64 -cpu host -enable-kvm -drive 
file=/root/qemu/w2k3_server.raw,if=virtio,aio=native -net 
nic,model=virtio,macaddr=52:54:00:12:34:56 -net tap,ifname=tap0 -localtime -
usb -usbdevice tablet -vga std -vnc :25581 -monitor stdio -m 512 -runas rick

Every now and again, qemu will up and quit leaving only the following message:
qemu: qemu_mutex_lock: Invalid argument

At the moment I can't stop what I'm doing to go learn how to debug qemu, but 
I'd be happy if anybody is interested in suggesting something I could do to 
provide some info about this bug...
Would it be helpful to build with -O0 -g and run in gdb, then get a bt when it 
dies?
I haven't put this into production yet, so I can still afford downtime & re-
compiles...etc.

thanks..

host machine is:
2.6.32-gentoo-r7 x86_64 Intel(R) Xeon(R) CPU E5450 @ 3.00GHz GenuineIntel 
GNU/Linux

guest os is Windows Server 2003, Standard Edition.  Service Pack 2.
Red Het VirtIO Ethernet Adapter Driver Version: 5.1.209.605
Red Hat VirtIO SCSI Controller Driver Version: 6.0.0.10

here is how I ran configure:
./configure --prefix=/root/qemu --target-list=x86_64-softmmu --extra-cflags="-
march=native -O2 -pipe" --extra-ldflags="-march=native -O2 -pipe" --audio-drv-
list= --audio-card-list= --disable-curses --disable-curl --enable-vnc-tls --
enable-vnc-sasl --enable-vnc-jpeg --enable-vnc-png --enable-vnc-thread

With the patch applied Qemu has not yet died in the fashion described above.
I will, of course, reply back if I encounter the failure again.
