Okay, whatever was happening on FC5 is still happening on FC7. Here's
what I've got today on a brand new install, same stuff I was using on
FC5 (IMQ, L7 and NAT-T) compiled on kernel 2.6.23.17-88.fc7:

Jul  6 12:12:01 backup2 kernel: kernel: fatal exception in interrupt

Those happened on openswan 2.4.12, 2.4.14 and 2.4.15. Right now I'm
recompiling without IMQ and L7 to see how it goes.

Unfortunately I can't fall back to 2.4.9 with kernel 2.6.23, so I'm
thinking about drop the ball on 2.4.x and move on to 2.6.x. But what I
really need to know is if bug #1004 is still biting. I read a while ago
on the list that it does not affect KLIPS, is that correct? If so, I can
go on and try it out. And what about multiple clients behind the same
router, is there any documentation available on how to set it up? Is it
possible with KLIPS?

Sorry about the overlapping questions, but I've searched around and
haven't found answers to those.

Thanks,


Giovani
