Panic on 8-STABLE in pfctl with options VIMAGE on a DELL PowerEdge R300 (bge)

[Onur Bektas]

Hi,

I had the same problem, I have updated the source tree and recompile the 
kernel  but the problem is  still unresolved..
pf + vimage = "kernel crash" problem was also reported as a bug..

Regards,

Onur.
