Works fine here under simulated high load that triggers the "timer out of sync".

@xeji Just out of curiosity, how did simulate the high load?

A combination of stress -c 4 (for my 4 cores) to get 100% CPU load and
cpulimit -e /path/to/qemu-system-x86_64 -l 20 -f to limit qemu to 20% CPU. Each alone wasn't enough but together they produced the error.
