FYI... these failures are getting more consistent on my octa board, but still not failing every time.

Hi Kevin,
Same here.
Observation: If you soft-reset the board (through the jumpers) after getting this problem, the problem keeps repeating. But if you hard-reset the board (by removing the power cord), the problem doesn't occur during next iteration.
I don't ever use the soft-reset, I only toggle the wall power. I don't ever actually remove the power cord though, I'm using a USB-controlled relay to toggle the wall power.

Laura,
We are getting following kernel panic [1] (not always, but quite regularly) while booting Arndale-Octa (based on Samsung's Exynos5420) board with upstream kernel. I haven't observed this issue with other boards yet.
This issue is observed when I am booting with uImage + dtb (within roughly ~10 iterations).
Some more information:
The boot logs are provided in pastebin, okay[2] and failed[3].
In case of boot failures, I am getting a higher value for vm_total_pages (684424 in [3]). In case of successful boot on my board, it is always 521232 [2] on my board.
I can confirm that reverting the "Get rid of meminfo" patch gets the Octa board booting reliably again for me also.
In case it helps, some boot logs for failures from the last copule linux-next build/boot cycles can be seen here: http://armcloud.us/kernel-ci/next/next-20140623/arm-exynos_defconfig/boot-ex... http://armcloud.us/kernel-ci/next/next-20140620/arm-exynos_defconfig/boot-ex...
