Where do you have uboot? SD or SPI ?
I've got my u-boot on SPI.
I noticed a bit of flakiness on bootup, which I've resolved by ejecting the SD card or by going via the boot menu. With the stock u-boot, I needed to eject the SD card to make things work at all, so this is an improvement.
When it fails to boot, it seems to get lost at the handoff from uBoot to Linux.
EDIT: I did find one regression. Under the stock U-Boot, sleep seems to be a no-op. With this updated U-Boot, the system is now capable of going to sleep, but it will never wake up. I disabled sleep and the problem went away.
