Also, I've tried setting hz to 20000000 but > encountered random errors. I ran tests for frequency that works dd out 1G of data from 8MHz to 16MHz, and it seems frequency less than 8.4MHz can only transfer at rate of 14.3MB/s and above 8.4MHz, speed goes up to 18.3 MB/s. Above 17MHz, errors encounters. hz1 8000000 73.5029 s 14.3 MB/s hz2 8000000 73.4740 s 14.3 MB/s hz3 8000000 73.3982 s 14.3 MB/s hz1 8200000 71.9677 s 14.6 MB/s hz2 8200000 73.4936 s 14.3 MB/s hz3 8200000 73.3462 s 14.3 MB/s hz1 8400000 56.6296 s 18.5 MB/s hz2 8400000 56.7616 s 18.5 MB/s hz3 8400000 56.7926 s 18.5 MB/s hz1 8600000 56.6622 s 18.5 MB/s hz2 8600000 56.7201 s 18.5 MB/s hz3 8600000 56.6476 s 18.5 MB/s hz1 8800000 56.8846 s 18.4 MB/s hz2 8800000 56.8226 s 18.5 MB/s hz3 8800000 56.7070 s 18.5 MB/s hz1 9000000 56.7007 s 18.5 MB/s hz2 9000000 56.6931 s 18.5 MB/s hz3 9000000 56.7465 s 18.5 MB/s hz1 9200000 56.7813 s 18.5 MB/s hz2 9200000 56.9230 s 18.4 MB/s hz3 9200000 56.8489 s 18.4 MB/s hz1 9400000 57.3411 s 18.3 MB/s hz2 9400000 56.5798 s 18.5 MB/s hz3 9400000 56.9512 s 18.4 MB/s hz1 9600000 56.6263 s 18.5 MB/s hz2 9600000 56.8361 s 18.4 MB/s hz3 9600000 56.9943 s 18.4 MB/s hz1 9800000 56.8875 s 18.4 MB/s hz2 9800000 56.7966 s 18.5 MB/s hz3 9800000 56.9299 s 18.4 MB/s hz1 10000000 56.7702 s 18.5 MB/s hz2 10000000 56.7131 s 18.5 MB/s hz3 10000000 56.7559 s 18.5 MB/s hz1 10200000 56.8087 s 18.5 MB/s hz2 10200000 57.0066 s 18.4 MB/s hz3 10200000 57.4178 s 18.3 MB/s hz1 10400000 57.0445 s 18.4 MB/s hz2 10400000 57.2470 s 18.3 MB/s hz3 10400000 57.3996 s 18.3 MB/s hz1 10600000 57.0698 s 18.4 MB/s hz2 10600000 56.9447 s 18.4 MB/s hz3 10600000 57.0124 s 18.4 MB/s hz1 10800000 56.8901 s 18.4 MB/s hz2 10800000 57.3534 s 18.3 MB/s hz3 10800000 56.7887 s 18.5 MB/s hz1 11000000 56.9826 s 18.4 MB/s hz2 11000000 56.8821 s 18.4 MB/s hz3 11000000 57.1497 s 18.3 MB/s hz1 11200000 56.6727 s 18.5 MB/s hz2 11200000 57.3771 s 18.3 MB/s hz3 11200000 57.2056 s 18.3 MB/s hz1 11400000 57.0076 s 18.4 MB/s hz2 11400000 57.1330 s 18.4 MB/s hz3 11400000 57.4008 s 18.3 MB/s hz1 11600000 57.1187 s 18.4 MB/s hz2 11600000 57.1042 s 18.4 MB/s hz3 11600000 56.9396 s 18.4 MB/s hz1 11800000 57.1824 s 18.3 MB/s hz2 11800000 57.0874 s 18.4 MB/s hz3 11800000 57.4669 s 18.2 MB/s hz1 12000000 57.0121 s 18.4 MB/s hz2 12000000 57.0706 s 18.4 MB/s hz3 12000000 57.0935 s 18.4 MB/s hz1 12200000 57.3944 s 18.3 MB/s hz2 12200000 57.5170 s 18.2 MB/s hz3 12200000 57.0330 s 18.4 MB/s hz1 12400000 56.8146 s 18.5 MB/s hz2 12400000 57.2807 s 18.3 MB/s hz3 12400000 57.1569 s 18.3 MB/s hz1 12600000 57.3627 s 18.3 MB/s hz2 12600000 57.2619 s 18.3 MB/s hz3 12600000 57.1370 s 18.4 MB/s hz1 12800000 57.3385 s 18.3 MB/s hz2 12800000 57.2734 s 18.3 MB/s hz3 12800000 57.0400 s 18.4 MB/s hz1 13000000 56.9019 s 18.4 MB/s hz2 13000000 57.1484 s 18.3 MB/s hz3 13000000 57.2854 s 18.3 MB/s hz1 13200000 57.3357 s 18.3 MB/s hz2 13200000 57.2955 s 18.3 MB/s hz3 13200000 57.1439 s 18.3 MB/s hz1 13400000 57.2260 s 18.3 MB/s hz2 13400000 57.3871 s 18.3 MB/s hz3 13400000 57.1127 s 18.4 MB/s hz1 13600000 57.4000 s 18.3 MB/s hz2 13600000 56.9386 s 18.4 MB/s hz3 13600000 57.4267 s 18.3 MB/s hz1 13800000 57.3932 s 18.3 MB/s hz2 13800000 56.8886 s 18.4 MB/s hz3 13800000 57.0506 s 18.4 MB/s hz1 14000000 57.2435 s 18.3 MB/s hz2 14000000 57.0724 s 18.4 MB/s hz3 14000000 57.3697 s 18.3 MB/s hz1 14200000 57.3237 s 18.3 MB/s hz2 14200000 57.3678 s 18.3 MB/s hz3 14200000 57.1647 s 18.3 MB/s hz1 14400000 57.1770 s 18.3 MB/s hz2 14400000 57.2560 s 18.3 MB/s hz3 14400000 57.4751 s 18.2 MB/s hz1 14600000 57.1345 s 18.4 MB/s hz2 14600000 57.2170 s 18.3 MB/s hz3 14600000 57.2803 s 18.3 MB/s hz1 14800000 57.0580 s 18.4 MB/s hz2 14800000 56.8908 s 18.4 MB/s hz3 14800000 57.0882 s 18.4 MB/s hz1 15000000 57.2161 s 18.3 MB/s hz2 15000000 57.3606 s 18.3 MB/s hz3 15000000 57.1794 s 18.3 MB/s hz1 15200000 57.1266 s 18.4 MB/s hz2 15200000 57.1371 s 18.4 MB/s hz3 15200000 56.6513 s 18.5 MB/s hz1 15400000 57.3680 s 18.3 MB/s hz2 15400000 56.9819 s 18.4 MB/s hz3 15400000 57.2429 s 18.3 MB/s hz1 15600000 57.4191 s 18.3 MB/s hz2 15600000 57.0848 s 18.4 MB/s hz3 15600000 56.9853 s 18.4 MB/s hz1 15800000 57.2306 s 18.3 MB/s hz2 15800000 56.9850 s 18.4 MB/s hz3 15800000 57.3068 s 18.3 MB/s hz1 16000000 57.1337 s 18.4 MB/s hz2 16000000 57.0935 s 18.4 MB/s hz3 16000000 57.2745 s 18.3 MB/s Thanks, Jeff -- 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/
