Aha... I thought the "0x42" was the problem, not "0x30". That was
going on and off for me for a long while. Actually, I don't think I
did anything special with USB gadget in this boot, and it is still
0x42.

Bit 21 is wifi, AFAICT. With right sleeps between reading the debug
file and talking to wifi, I now get:

Battery 4.16V 4.18V 4.14V 95% 93% 100% 1569/1569 mAh Charging
49/650/1800 mA
fffffebd 48004a20 (fa004a20) cm_idlest1_core blocking bits: 00000042
Battery 4.16V 4.18V 4.14V 95% 93% 100% 1569/1569 mAh Charging
48/650/1800 mA
fffffebd 48004a20 (fa004a20) cm_idlest1_core blocking bits: 00000042

0x02 seems to be SDRC.
0x40 seems to be OMAPCTRL

I get

0x18000 randomly, too. That should be I2C1, and I2C2. But even when
idlest1_blocking_bits are 0x42, the left and right backlight on
keyboard is lit constantly -- not blinking -- indicating that it is
still not sleeping.

Full debug is:

Anything else I should look at?
