int_osx_receive_prim() in gsm-fw/gpf/osx/osx.c: there was an error in the reconstruction of this function from disassembly in the logic that implements special handling for MPHC_RXLEV_REQ messages. The code is now fixed to properly match what the binary object version does; with this fix the firmware now performs the power measurement phase correctly and the initial network registration succeeds.
