These look like a broken driver, not an UBI/UBIFS problem. Try to run MTD tests and validate your driver in the modern kernel first. The MTD tests are kernel module, they work by insmoding. You should find some info on the MTD website. -- Best Regards, Artem Bityutskiy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
