The diffstat from yesterday is very light, nothing jumps out as being a likely cause.
Could it be a bad MMC card?
It's possible, it's Kevin's lab so he'd need to take a look.
I changed MMC cards, and it's happier now.
OK
What's strange is that it was succesfully loading/booting u-boot from MMC, and the card and partitions etc looked fine in a linux pc. Anyways, it's changed out now.
Weird. I guess it's still possible we have some regression for lower voltage cards then.
Hmm, I think I spoke to soon, and now I don't think it's the MMC card.
I'm still seeing periodic failures on this board soon after the MMC init, but only in mainline and next: https://kernelci.org/boot/omap3-beagle-xm
Also, looking at that URL, you'll see that the failures are only for multi_v7 but not omap2plus_defconfig.
The step that seems to be happening right after MMC init is unused regulators being disabled. Is it possible that multi_v7 is missing some regulator setup?
Also, the last line in the failure case:
leds_pwm pwmleds: unable to request PWM for beagleboard::pmu_stat: -517
doesn't happen on the successful omap2plus_defconfig boots either.
