I don't think you told us the kernel version?
There have been recent fixes wrt sizing of the BIOs which the direct-io layer sends down. So please make sure that you're testing Linus's current -bk, or 2.5.42 plus
http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.42/2.5.42-mm2/broken-out/dio-bio-add-fix-1.patch
Either that, or raid5 is bust ;) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
