This is probably not a kernel issue but a madwifi
issue, but figured I might as well post in both areas.
I am running a small test of having one computer act as a shoutcast
server with SELinux and ipsec(total lockdown), then another computer
act as a costumer
with SELinux and ipsec both with AH and ESP encryption;
Everything looks good both boxes are sending and receiving
AH and ESP encryption without any problems, except for a warning:(below)

At first I was having internet connection, and then a few minutes
later nothing, but realized it was ipcomp that I didn't load.
When this error occurs the music is streaming, then cuts out
for a few seconds, and then back to streaming music.

In any case could be madwifi, could be the kernel,
better to send a post, than ignore it.
