well i'm not sure we talk about the same ROM but i would like to test this Kernel with the latest CM10.2 nightly.I'm facing the same RIL problems since CM10.1, now I'm trying this kernel, is awsome, but the baseband still change after reboot, and mobile data network get stuck after a while, did you solve your problem?
with my current setup: Optimus Play and latest nightly i've got quite a stable mobile and data network but a very poor deepsleep based on Baseband_xmm_power and Wlan_rx_wake kernal wakelocks. so i hope with this kernel to find a good deepsleep too
but for now first i have to do a complete fresh install to see if it would boot anyway. until now it's not booting.
