linux-armv7-4.5.3-1 breaks SabreSD board

[maso]

I ran a pacman -Syu yesterday my SabreSD stopped booting.

After a reinstall and systematically updating each base package, then seeing if it rebooted, I narrowed it down to linux-arm7-4.5.3-1

So if I use ArchLinuxARM-armv7-latest.tar.gz (as of 5/10/2016), it will make it to command prompt fine.
Then, following pacman -Syu and a reboot, the system locks up after beginning to load the kernel. I never see "Welcome to Arch Linux ARM!" in the boot roll.

Is there anything I can do to recover my system from yesterday?

Chroot from another arm device (orthe same device with a different rootfs) and install a older kernel.
If you can't find an older kernel I have it available here: https://olegtown.pw/archlinuxarm-archiv ... nux-armv7/

Thanks! I'll give it a shot tomorrow.

Meanwhile, I've discovered that the latest ArchLinuxARM-armv7-latest doesn't recognize any USB devices, and /dev has maybe 1/4 as many devices listed as with an older image. It's not outputting to HDMI, and most peripherals are missing.

That's from fresh boot, no pacman updates at all. Something bigger has definitely broken for the SabreSD since my last update (maybe 6 months ago). I'm starting over with an image from a year ago.

Update:
I dug into my old pacman.log, and my previous update had been 3/28/16, which had worked.
Here's a list of everything that was upgraded on 5/9:

I have the same issue on the Wandboard (i.MX6 Quad) and had to revert to 4.5.2-1
