--- Comment #26 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
Did you add this extra debugging statement for "executed %d iterations"
somewhere? I've never seen that in kernel code before. I guess you're
counting the number of s2idle loops?
The patch aims to track down the issue of not being able to read from the RTC in cases of being in s2idle for more than approx. 2,5 days.
Can you please turn on /sys/power/pm_debug_messages as well? It's a bit weird
to me that the loop would run that many times in the first place. That means
the hardware has been returning control to the kernel a lot more frequently
than expected (and maybe that's allowing to trigger this issue).
I'll do so.
