Hello,
After 3 straight days of wrongly debugging the megaraid_sas source code,
I believe I found the proper work-around/solution for this situation.
Setting linux kernel boot parameter pci=conf1 allows my Intel RAID
Controller-RMS25PB080 (LSI 2208/Fusion based) to be detected, and the FW
to transition to Ready state. Without this setting the Card FW responds
only with 0xF0000000 Fault (Masked).
I found linux kernel series 3.0.0, properly discovered and used the RAID
card. Things broke for me in kernel series 3.2.0, onward. So there
seems to be ?broken? PCI discovery on my Intel s2600 system, using the
Intel/LSI 2208 card
My System Details:
Card PCI ID: 1000:005b
Card PCI description: LSI Logic / Symbios Logic MegaRAID SAS 2208
[Thunderbolt] (rev 03) aka Fusion
Card Firmware Version: v23.9.0-0018 (most current to-date)
Card OEM: Intel RAID Module (Card) RMS25PB080 SAS
System Board: s2600CP - E5-2600 Xeon, LGA2011 Socket
System Firmware BIOS level: 01.06.0002 2012/11/15 (most current to-date)
Best Regards,

Hello everyone, hello Michal,
I can confirm and reproduce this issue on a different set of hardware:
Intel S1200BTLR Mainboard
LSI MegaRAID 9266-4i Raid-Controller
I haven't tried using a kernel older than 3.2.5 so far, but with kernels
3.2.24 and 3.5.0 I get the following dmesg output:
[ 2.621164] megasas: 00.00.06.15-rc1 Mon. Mar. 19 17:00:00 PDT 2012
[ 2.621179] megasas: 0x1000:0x005b:0x1000:0x9269: bus 1:slot 0:func 0
[ 2.621599] megasas: Waiting for FW to come to ready state
[ 2.621601] megasas: FW in FAULT state!!
As a result I can't access any drives connected to the controller.
Tested Controller firmwares: 23.7.0-0031, 23.7.0-0035 and 23.9.0-0015
Tested Mainboard BIOSes: R0037 (BMC 1.14, FRUSDR 1.14)
I contacted Intel and LSI support a while ago. Intel shot me down by
telling me this wasn't their problem. LSI at least tried to resolve the
issue but thus far failed to do so.
Unfortunately I don't have access to the system on a day-to-day basis,
but I will test eventual fixes as soon as I get the chance.
