I've ran it several times now, and I haven't got PCM0P to load:

I'm on top of sof-dev, but in my previous log I had the verbose IPC 
logging option off.
I'm currently running with the timeout values set to:

core.c:
#define TIMEOUT_DEFAULT_IPC_MS  3000
#define TIMEOUT_DEFAULT_BOOT_MS 10000

ipc.c:
#define IPC_TIMEOUT_MS         3000

Those seem like pretty high values for me, compared to the initial ones, 
but I'll try to increase those even more - maybe that fixes it.
