Related function (pdch.cpp):

void gprs_rlcmac_pdch::rcv_resource_request(Packet_Resource_Request_t *request, uint32_t fn, struct pcu_l1_meas *meas)

In there, osmo-pcu correctly handles Pkt resource Request if the MS identifies using TLLI, but it does not if MS used Global TFI (for instance if the MS has already a Downlink TBF established).

There exists already a log ERROR to warn about it not being implemented, I just run through it on my local setup a few seconds after turning on my phone:
