The zeros look like there are no timing interrupts happening. It's a pity we don't have hardware to test which kernel version introduced the bug (for instance with git-bisect and reboots).

I think the zeros are normal here, on other machines, the values actually start to change just after this line.

They are completly normal and I'd be happy if people disable CONFIG_PRINTK_TIME for readability when posting kernel messages.

Try turning off SMP. I have a 1480 (big sur) board. I just tried 2.6.28.9. This is 32 bit, little endian mode. With SMP turned on, it hung in the same place. With SMP turned off, it booted fine.
