Hello, I'am using a LSI 1068e OEM version from Super Micro (see lspci). I was able to install a plain CentOS5 with the binary drivers I got from Super Micro. 06:00.0 SCSI storage controller: LSI Logic / Symbios Logic Unknown device 0059 (rev 04) Subsystem: Super Micro Computer Inc Unknown device a180 Flags: bus master, fast devsel, latency 0, IRQ 10 I/O ports at e000 [size=256] Memory at febfc000 (64-bit, non-prefetchable) [size=16K] Memory at febe0000 (64-bit, non-prefetchable) [size=64K] Expansion ROM at fe800000 [disabled] [size=2M] Capabilities: [50] Power Management version 2 Capabilities: [68] Express Endpoint IRQ 0 Capabilities: [98] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- Capabilities: [b0] MSI-X: Enable- Mask- TabSize=1 But if I try to load the XEN kernel or a newer kernel all I got is a kernel panic, because the new kernel does not know about the megasr.ko module that I installed from disk. So I did the following (without final success): - cp /lib/modules/2.6.18-8.el5/updates/* /lib/modules/2.6.18-8.1.15.el5/updates - depmod -a 2.6.18-8.1.15.el5 - created a new initrd-cpio file and copied megasr.ko into the lib directory The systems starts loading the kernel and its ramdisk, and then hangs: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) I'am a bit lost, what else I can do to get this working?
