I've not yet seen this.  A quick look at the source...
   
http://cvs.opensolaris.org/source/xref/on/usr/src/uts/i86pc/io/pci/pci_boot.c#12
41
 
... seems to indicate that it is trying to find an unused portion
of 256 bytes of I/O space (for the NIC (?) at pci bus/device/func 0/3/0,
according to the command "info pci" in qemu's monitor), and has failed.

Time of  Day clock

I also get this warning from time to time.  Sometimes the reason is 
that clock is "stalled", sometimes it has "skipped".  It seems to be a
harmless warning, though.

Try to boot with the kernel debugger enabled, so that you can read
the panic message (I guess it reboots because of a panic).
In the GRUB boot menu, type "e" twice to edit the boot commands,
and add options "-kv" at the end of the "kernel" command line.
<RETURN> and "b" boots with the kernel debugger and verbose kernel
messages enabled.

Is that the host OS or the guest OS?

Are you running qemu or qemu-system-x86_64?

With or without kqemu?

Are you trying to install open solaris, or are you trying to boot from an 
installed qemu hdd image?
