First a simple test to do is to increase the boot timeout in driver loader.c:
» ret = wait_event_timeout(sdev->boot_wait, sdev-
boot_complete,
» » » » msecs_to_jiffies(sdev-
boot_timeout));
I did hit occasionally that the DSP-side QEMU was too slow to respond and simply bumping this timeout help.
Indeed, after increasing the values for the default ipc and boot timeouts (TIMEOUT_DEFAULT_IPC_MS, TIMEOUT_DEFAULT_BOOT_MS, IPC_TIMEOUT_MS) I got it it to boot. I'm still getting errors when loading the topology, though:
Are the topology loading errors always at the same place or does it vary on each attempt ?
I've ran it several times now, and I haven't got PCM0P to load:

Btw, what kernel version are you using. Recent version of sof-dev branch will print out additional debug for IPC timeouts.
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.
