kqemu locking my machine hard on amd64 smp, with most recent patches

Thu May 15 02:53:22 UTC 2008

Hi Juergen.  No, I'm running it in a screen session on a headless  
machine and using VNC as a display device.  I run it from the console  
and it hangs before anything useful shows up.  Specifically, it spits  
this out before hanging:

oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
audio: Failed to create voice `pcspk'
pcspk: Could not open voice

So yeah, it's complaining about the sound hardware.  Anyway, if I  
watch it in VNC, it hangs immediately when trying to boot the linux  
kernel; the only VM I've tried with it is a kubuntu install.  It goes  
through the BIOS init, kicks off grub, and then says "Starting up ..."  
and then hangs.

I've attached my dmesg.  Thanks for whatever time you can put into this.

Todd
