Usually when I come across a system like this, Ijust flash the firmware to an IT mode so we get just an AHCI system with JBOD, but sometimes it is not practical for remote systems or if we fear that flashing is too risky if something goes wrong.
In this case, we unfortunately have to use LSI/Broadcom proprietary CLI tools (megacli) to even make the drives visible.
Step 1 - Download MegaCLI
The official broadcom packages lack .deb packages and only have .rpm for........

It looks like this has something to do with APIC but I am not sure. I have similar CPUs with a different MB and BIOS that work fine on the same type of kernel. A lot of time the issue is because of the C-step setting in the BIOS.
The same thing happened on the 2.6 kernel with Centos 6 but this is a homebrew 4.4 kernel soI am not sure why it is happening when even Centos 7 (3.2) kernel works OK.
Solution - It comes down to the BIOS set........
This happened after a customer migrated their hosting and the issue was being unable to access PHP sessions.
Warning: session_start(): open(/var/lib/php/session/sess_3e0oms763m6mrqekdnnmodlhs3, O_RDWR) failed: Permission denied (13) in /register.php(202) : eval()'d code on line 1
Solution:(use the correct ownership/permissions)
chown apache.apache -R /var/lib/php........
I decided on using yum to help me decide even though I normaly use proftpd I decided to see what else I could find.
