Per investigation, looks like set_next_event() now receives too small delta and fails with -ETIME. Google group discussion: https://groups.google.com/forum/#!topic/vt8500-wm8505-linux-kernel/vDMF_mDOb1k v2: Address comments by Alexey Charkov. Merge patches to get less amount of changes (three patches instead of four). Tested on my WM8650, no issues in three days uptime.
