Has anyone tested this firmware? Is it free from this error message "Parity<br>
Error on path"?<br>
Thanks any information.<br>

P20 firmware is known to be toxic; just google for "lsi p20 firmware"<br>
for the carnage.<br>
<br>
P19 and below are fine, as far as I know.<br>

I've not heard good things about 19. I HAVE heard that 18 is the best level of FW to run for right now.<br>

Thanks!<br>

Is there a known good way to flash a LSI back to P18 if it already came with P19? I happen to have two new LSIs running P19.<br>
Afaik, the readme explicitly warns about flashing back the fw…<br>
