 no, this last panic was when booting from an FFS partion (all is FFS here, 
 only got a vnd with LFS). During the startup of the system when it just 
 printed `starting syslogd' it panic'd.
 I'll have to excuse you... it turns out that the kernel propably is 
 somewhere due to my patch. A bog-standard kernel seems to run fine. I'm 
 looking into this now. It runs fine though when DIAGNOSTICS is on it 
 somehow failes a check.

 I could imagine other places would have this hidden dependency on bp->b_vp 
 being NULL when they request it. It was meant as a reference to the 
 suggestion to put this statement in the BUF_INIT() macro.
