Ok, so it seems to be:

user@devuan:~$ cat /sys/kernel/debug/pm_debug/count
(oops).

The file seems to be world-readable.

user@devuan:~$ ls -al /sys/kernel/debug/pm_debug/count
-r--r--r-- 1 root root 0 Jan  1  1970 /sys/kernel/debug/pm_debug/count

But on PC, that file does not exist.

Any ideas?

I'm not seeing this as tested with omap2plus_defconfig and
not seeing any unclocked module interrupts here.. Can you
see if the script below produces something for you?

I had to filter out some trace pipes as they seem to hang.

After some more debugging:

+       printk("3...\n");
        cm_per_dump(s);
+       printk("4...\n");

cm_per_dump seems to be the problem.
