Thanks for helping debug the issue and taking the useful dmesg log.
From the dmesg log, the ECC error log register of this SoC contained the
invalid error value ~0, resulting in a flood of invalid error reports in polling mode.

@Ramses & @John,
Can you please apply the attached fix patch and see whether it fixes the issue?
Thanks!
