Then connection is not dropped but times out after a while with no traffic going in either direction. The problem is always reproducible. >How-To-Repeat: Build a kernel with ADAPTIVE_GIANT or PREEMPTION options enabled. Install and configure port mpd-3.18_2. Start mpd daemon. Establish a connection and begin transfer. After a period of time the above message is always logged and a connection stalls. >Fix: Remove PREEMTION and ADAPTIVE_GIANT options from the kernel and add NO_ADAPTIVE_MUTEXES option. Rebuild kernel. Reboot. Launch mpd daemon. No connection drops happen. >Release-Note: >Audit-Trail: >Unformatted:
