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, Ron Allred > -- > 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.
