OT: FC5 2107 build - bad networking?

Before I go bothering the bugbase or other lists, does anyone else lose 
networking connectivity with the new kernel-smp-2.6.16-1.2107_FC5 just 
pushed out for FC5?

My interface comes up and basic ping works, but no applications at all 
"finish" (GAIM logins, Firefox gets, etc.) It's reminiscent of way back 
when in older kernels that tried to set that packet option that was 
getting killed on a lot of routers (I forget the name, it was eventually 
turned back off).

Thanks for any 411 - the previous 2096 kernel works perfectly of course.
