The errata ID is not correct. I believe that 1P153 is referring to the section number in the errata doc and not the errata ID. The errata ID should be i451 in the latest OMAP34xx and OMAP36xx docs.
Please can you update this? The section number changed in the latest errata docs and it took me a minute to find this.
