gsm_04_08_rr: silently ignore RR UTRAN Classmark Change
Some UMTS capable phones (such as SE K800i) send this message together with the 'normal' RR Classmark Change, what makes osmo-bsc log the following warning: DCHAN NOTICE gsm_04_08_rr.c:1037 lchan(0-0-1-SDCCH8-0)[0x562ea76d3ab0]{ESTABLISHED}: (type=SDCCH) Unknown RR message: UTRAN Classmark Change We don't handle it, so just ignore without logging anything.
