Have a customer running FC5 with a 22.214.171.124 kernel (no, sorry, they can't upgrade because of other hardware and software dependencies).
Need to find a PCI or PCIe SATA RAID card that'll handle four drives in a RAID5 array and work with FC5 126.96.36.199 kernel.
I do have the ability to modify the kernel, if the card has support for that old of a kernel. I've tried some newer cards with support for 2.6.2x and the drivers are just too new.
Any suggestions? Need something that is currently available as a new product today, as this might be an ongoing deployment. Don't really have the ability to use used hardware.
