I believe P20 had trouble. P19 seems to work fine. > > https://www.centos.org/forums/viewtopic.php?t=50032 Thanks Mikael, Read it and did more searching. The latest I found is this (a year old): https://forums.servethehome.com/index.php?threads/tutorial-updating-ibm-m1015-lsi-9211-8i-firmware-on-uefi-systems.11462/ and it closes by saying: P20 Myth There are many revisions of the P20 firmware. The first few had lots of bugs so people suggest avoiding it. However, someone pointed out that all versions that are 20.00.04 and after are fine. I using the current latest version 20.00.07 and have had no problems. Did a full scrub, bonnie benchmark, copied large files and played them back with no errors. I was looking for a URL to download the necessary files but the official sites removed them. The one linked from the above blog contains the files, is it reliable? https://www.mediafire.com/download/6mtie10d9ud6675/LSI-9211-8i.zip It contains: $ strings -a 2118it.bin | head -n 1 @(#)MPTFW-20.00.07.00-IT $ md5sum 2118it.bin 8d8cd74b8080bbe100aedb8dff092301 2118it.bin Is there a known good/safe site for these files?
