It seems to be a host kernel problem.

G'day all,
Just wonder if anyone else is seeing this. I've not had a chance to
track it down or try to debug it yet.
I'm running latest QEMU CVS with kqemu and the -no-tsc patch on a
vanilla 2.6.17.3 kernel with suspend2.
The VM behaves perfectly until I do a suspend/resume of the host. When
the machine comes back, most of the time (not all the time however) it
ends up flooding my logs with this message.
Jul 8 17:26:03 localhost kernel: [43299223.910000] rtc: lost some
interrupts at 1024Hz.

interrupts at 1024Hz.
Jul 8 17:26:03 localhost kernel: [43299223.970000] rtc: lost some
interrupts at 1024Hz.
Of course if I shutdown/reboot the VM the problem goes away. I've seen
this before but it's been a while from memory.
I'm running a vanilla 2.6.17.3 kernel in the guest booted with GRUB and
both host and guest are configured with HZ=100.
I seem to recall mplayer does the same thing if I leave something
playing over a suspend/resume, but I've not had a chance to look at it
further. It's pretty reproducible here with qemu anyway.
This is about the only remaining thing that is preventing me leaving
VM's up over suspend/resume now. Other than that, it's all good.
I'll probably get to looking at it in the next couple of weeks if nobody
has any pointers.
