Bryan, I'd suggest you to test your NAND driver with the following NAND tests: git://git.infradead.org/~ahunter/nand-tests.git (http://git.infradead.org/?p=users/ahunter/nand-tests.git;a=summary) You may want to avoid the torture test, but it is useful to run it with limited amount of erase cycles to make sure your flash/driver survives really high I/O load.For example, we caught occasional DMA transfer problems while running the torture test for few days. -- Best regards, Artem Bityutskiy (Битюцкий Артём) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
