On some products that use the Gumstix Overo, we found microSD card failures during extended NAND read/write tests. Again, the fix suggested by TI was to increase the dto timeout value to 14. The issues were more apparently with cheap microSD cards, not necessarily the faster class 4 variety. Using a SanDisk class 2 works ok. I used a SanDisk class 4 for development. The microSD card gets corrupted when running endurance tests, with failures occurring with the microSD card in about 3 to 4 days of doing continuous read-writes to the microSD card.
