[Qemu-devel] qemu: qemu_mutex_lock: Invalid argument

[Qemu-devel] qemu: qemu_mutex_lock: Invalid argument

[Rick Vernam]

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..

Can you try the patch above?  If it works, I need to ask Anthony to
pick it up for 0.13.

Thanks,

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.

I have not encountered this problem since applying the patch.  So I sure would 
like to see it in 0.13.
