Hi,
I'm not sure if this will be of any help, but :
- I had really old Pluto installation and on upgrade for 0.40 I got all sorts of weird problems (for instance crashing pppoe that noone else reported, even in Debian community)...
Then I went with fresh install and problems went away, also I had kernel modules crashing (pwc,zpca50x), but those problems vanished on 0.41....
I'm not sure if any of this applies to your case, but I just felt that maybe it will be useful in some cases...
HTH,
Rob.
