I just deployed 10 R610s which have this controller with CentOS 5.2, I later upgraded their kernels to the latest from 5.3, though the rest of the systems are 5.2. Of course the drivers are part of the kernel not the rest of the space. 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04) Subsystem: Dell PERC 6/i Integrated RAID Controller Flags: bus master, fast devsel, latency 0, IRQ 177 Memory at df180000 (64-bit, non-prefetchable) [size=256K] I/O ports at fc00 [size=256] Memory at df1c0000 (64-bit, non-prefetchable) [size=256K] Expansion ROM at df100000 [disabled] [size=32K] Capabilities: [b0] Express Endpoint IRQ 0 Capabilities: [c4] Message Signalled Interrupts: 64bit+ Queue=0/2 Enable- Capabilities: [d4] MSI-X: Enable- Mask- TabSize=4 Capabilities: [e0] Power Management version 2 Capabilities: [ec] Vital Product Data Capabilities: [100] Power Budgeting I was also able to run R610s under CentOS 4.6 without any issue as well. nate
