Somewhere in between 3.3.x and 3.7.x I managed to lose PIMV1 and PIMV2 support in the kernel configuration, and also lost the NO_HZ and faster clock I'd had there too. CONFIG_NO_HZ=y CONFIG_HZ=256 CONFIG_HZ_256=y As well as the other TCP variants like VENO and LP (I think, I might have added them elsewhere) Checking into that latter bit as well as into the unaligned traps tonight (unless someone beats me to it) > Regards, > Maciej > > >> > > >> or perhaps I did something stupid regarding igmp.
