It looks like commit fb2c599f056640d289b2147fbe6d9eaee689f1b2 ("ARM:
omap3: enable off mode automatically") is causing these failures on the
Nokia N900. Reverting this commit on top of v5.10 (with
21b2cec61c04bd175f0860d9411a472d5a0e7ba1 also reverted), makes the
problem go away (I tried 10 times).
The same holds for 5.15.y, just reverting
fb2c599f056640d289b2147fbe6d9eaee689f1b2 makes the system "stable" (at
least the problem reported in the first email is gone).
Perhaps the "pwrst->next_state" change is causing these problems, since
I can enter OFF mode just fine with init=/bin/sh and a custom script?
Cheers,
Merlijn
PS: Nikolaus - might be worth getting that N900 going some time soon. ;-)
PPS: Looks like there is a regression between v5.7 and v5.9 where OFF
mode is no longer hit normally (I hacked around that for my 5.15.y
branch, but this is *not* what is causing the problems here). I'll try
to bisect that regression later. I think I was able to hit 7mA at 3.8V
with v5.7, so that's worth bisecting I think.
