Huh. Yea, that looks fine. And without the
__timekeeping_inject_sleeptime() call, the system resumed ok?
Yes, it does.
So I'm mostly still stumped on this. But I did find one possible related
bugfix that maybe you can try?
Let me know if the patch below dodges the problem, and if not, please
send me the JDB printk output.
(if the resume hangs without any output, add a "return;" before the
tk_xtime_add() call between the JDB printks).
thanks
