 Do you remember exactly when that happened?  I'm pretty sure I tried to 
 build qemu right after the fix was committed, and my machine still 
 crashed.  So, if you have the date, I'll roll back the kernel to that 
 point and try again just to make sure I did the correct thing back then.

 Probably.  I just would like to revalidate according to when the fixes 
 happened.

 Agreed.
