I'm experiencing random disconnections of my WiFi. I've tried the kernel 3.2.0-sabayon from weekly and now I'm on 3.2.0-sabayon-r12 from limbo but still, sometimes the WiFi connection drops and reconnects by itself.
I had the same problem on Fedora 16 (x86_64) on kernel 3.2.3 and I had to switch back to 3.2.1. (the bug in Fedora was reported here: https://bugzilla.redhat.com/show_bug.cgi?id=785239
-- if it helps in some way)
