>Description:
This bug is a placeholder, since I don't know exactly what triggers the crash.  However whilst experimenting with bringing up IPv6 connectivity I managed to crash my box several times.

My suspicion is that destroying an stf interface triggers a delayed crash.
>How-To-Repeat:
Unknown.

Possibly triggered by destroying an stf interface.

 It should be noted that I run dummynet, so this could in some way be
 related to the known problems with destroying interfaces when using
 dummynet.
 
 Although obviously I'm not using dummynet with IPv6, since that's not
 supported in 5.4...

State-Changed-Why:  
Roy, 
we do not want to have 'placeholding bug reports' w/o any information 
to work on a bug report. If your system crashes, we need more specific 
information (at least a backtrace from the crash). 
Please note, we were fixing some stf related panics lately. 
Please upgrade your system to 6.4 or 7.1 (or 6/7-STABLE, HEAD) and 
report back if you still experience the bug.
